8 steps to retrieve a lost SharePoint document

SPdocgone-header2We frequently get calls from colleagues whose documents have “disappeared” from their SharePoint site. Over time, we have come up with a few steps to investigate and (often) find them.

They are comparable with the steps taken when you misplace a OneDrive document, but finding lost documents in SharePoint is a bit more complicated than finding them in OneDrive:

  • Other people can edit or delete documents
  • You only have 1 OneDrive (which is one document library), but you probably work in multiple document libraries in multiple SharePoint sites
  • Permissions can vary within and across sites

On the plus side, there is a Site Owner and a SharePoint admin who may be able to help you out!

What could have happened?

These are the most frequent “disappearing acts” of documents:

  • Deleted (deleting a synced folder without disconnecting it first also deletes the documents from SharePoint!)
  • Renamed
  • Moved to another folder in the same document library
  • Moved to another library in the site
  • Moved to another site. This means the original document has been deleted.
  • Moved to your OneDrive
  • Permissions have changed and you no longer have access
  • Metadata have changed so it appears in a different view than usual

Which tools are available?

  • Search
  • Recycle bin
  • The document details pane
  • The site owner or your SharePoint admin

Where to start?

Just like my post about the disappeared web parts and lost documents on OneDrive, I have thought about the best possible order to use the available tools. It may appear to be fastest if you go to the Recycle Bin first, but that may be quite a chore if your site is active, your document has been deleted some time ago and/or document name, the author or the suspected deleter starts with M or N. Sadly you can only Sort, and not Search, in the Recycle bin.

My suggestion would be to first try and find the document in the original library. But please, feel free to disagree! It also depends…:)

1. Search in the Document Library where it used to live

Found it? Open it to see whether this is the document you are looking for. It has most likely been moved from one folder to another, or metadata has changed so it appears in a different view. Take step 2 to find the location if you do not see it straight away and/or confirm with step 7 to see what exactly has happened if you are curious.

SPdocgone-searchlibrary
There are two documents in this library. You can click to open them from there or click “Show more results”

No luck? Move on!

2. Search in the SharePoint site

You can easily do this by clicking “Expand search to all items in this site” on the bottom of the Search results page from step 1.

SPdocgone-searchlibrary2
You do not get any more results in this case, nor the exact location of your documents, but this view allows you to expand search and that will give you more info.
SPdocgone-searchlibrary3
So there is another result if you search in the site. If you get too many results, you may want to use the Files tab and/or the Filters to narrow down. And…this view will show you the path of the document!

Found it? Note down the path and navigate to it to confirm this is the correct document. The document has been moved to another library. Confirm with step 7 if you feel the need.

No luck? Move on!

After this, you can do what is most easy for you.

3. Search from the SharePoint landing page

Found it? Well you are lucky! Unless your document has a very unique name, it will be hard to find between all the other documents in your organization. (Of course, using the Files tab and the Filters should help a little). So, it has been moved to another site. Note down the path and confirm it is the correct document. Confirm with step 7.

SPdocgone-spsearch
Results from SharePoint search. In this case you get results from all of SharePoint, so it will be necessary to narrow down the results by using the Files tab and the Filters. You see there is also a result from OneDrive.

Results from OneDrive are also shown in SharePoint search, so if you have accidentally moved the document to OneDrive, you will find it there as well. Unless you want to know WHEN you did this, there’s no need to confirm with step 7 as you are the only one who could have done this. 🙂

No luck? It has probably been deleted, renamed or had its permissions changed (with or without moving). Take any of the next steps to find out.

4. Search in Office365

Frankly, chances are slim that you will find it here but you can try! If it is not in OneDrive and not in SharePoint (including Teams) it may be in Outlook or Yammer but would you not remember if you have done that? But, just to be on the safe side, give it a try.

Found it? Congratulations! Now move it back to where it belongs!

No luck? Well, you really did not expect to find it after all your other trials, right? Time to look in the Recycle bin.

5. Check the Recycle bin

Found it? Restore it.

No luck? Move on!

6. Ask the site owner if they know, or to search in Library or Site

Found it? It has probably moved to a place to where you do not have access, or you have actively been removed from the access group. Discuss with the site owner to give you access again, if possible.

No luck? Move on.

7. Check the Document Library’s details pane

In some cases you may want to do this earlier, but especially in a busy SharePoint site you need to scroll a lot! If someone knows a good way to export the data into a nice Excel file or something, please let me know.

The details pane is context-sensitive and will display different details depending whether you are on the document library landing page or in a folder.

DisappearedDocs-infopane
Nice icons, clear descriptions and clickable links for documents that are still in this folder or library. Deleted documents are not clickable.

Found it? Confirm it is the correct document and note down the path and/or new name.

No luck? There is one last option…to be done when all else fails.

8. Ask your SharePoint administrator

Your SharePoint admin will likely have permissions to everything so if they can not find the document in Office365 search, it will not exist in its original shape anymore.
Additionally, they can also check the 2nd stage Recycle bin to see if it has been deleted.

Found it in Office365 Search? Confirm it is the document, note down the path and ask the site owner to give you permissions again.
Found it in the 2nd Stage Recycle bin? Ask your SharePoint admin to restore it.
Confirm what has happened with step 7 and give your SharePoint admin a compliment on Yammer or Teams for everyone to see! 🙂

No luck? Sorry….

Any other thoughts?

Did I miss something? Do you think there is a better order? Any other tricks to share? Please let me know!

An alternative way to dive into Delve

Delve-headerDelve is an interesting part of Office365.

In my previous organization I often received complaints about what was shown in Delve. Exactly like the results you see in Search, what you see is what you have access to, and for many people this was hard to understand. Every time the Search or Delve results got questioned (“Search is broken!”) I could prove that this person saw this search result or this document card on Delve because they had access to it, whether that was desired or not. I loved this demonstration of the importance of proper permissions management 🙂
In Search, any mismanagement of permissions only becomes apparent when you are actively searching, but in Delve “content finds YOU” so it is ruthlessly in-your-face.

Joanne Klein has written a great post on Delve and how to disable it – entirely or partially.

In my current organization we have not promoted it very much yet, so when we recently changed a number of licenses from E1 to F1, we did not consider the fact that the Delve app would no longer be visible for the F1-users, a big risk.
However, we received a question from someone who uses the people-part for looking up managers and direct reports, so I found three alternative options.

1. Via “My Office Profile”

After all, the Delve “Me” page is your profile page, so that should be available for every user. Just click on your picture top right and select “My Office profile”.

Delve-myprofile
“My Office profile” leads to your Delve “Me” page

 

2. Via the URL

Delve is available for users if they are logged in to Office365 and use the following URL: https://<datacenterlocation&gt;.delve.office.com.
For our organization and my own tenant this is https://eur.delve.office.com and for a tenant in the UK this would be https://gbr.delve.office.com
I do not have access to any other tenants so I can not give you the “code” for other data centers but please take a look at your Delve to see what it is. It may come in useful one day.

Delve-Mepage
My Delve page. The URL will resolve itself to yours as soon as you enter the URL.

3. Via Outlook (people data only)

Like Delve, Outlook also uses Active Directory so all people data is also in Outlook.
Users with an F1-license use the Outlook On The Web experience and they can see people’s managers and direct reports in the people card.
When you hover over a person’s name (searched or from an email) you will first see the small card, which expands into a larger card. When you click “Show more” you will see a ton of info, including the “Organisation” which will allow you to see a person’s manager and direct reports. In my case the tab is greyed-out because I am the only one in my tenant and have not set up AD.

Delve-Mepage2
Lots of info available if you click “Show more” on the extended hover card. The “Organization” tab will show you direct reports and managers.

4. “Discover” on the Office 365 start page (documents only)

The Home page in Delve shows a mix of documents that are popular or have been edited recently by people you work with.
The Office365 homepage has a tab called “Discover” which shows you a mix of recent documents from others.

Delve-discover
The “Discover” tab, showing you a mix of documents from your “circle”.

When I compared the two I found these were very similar except for

  • Content: the “Discover” tab on the Office365 homepage only shows documents from OneDrive and SharePoint, while the Delve page shows documents from OneDrive, SharePoint and Outlook
  • Display: Delve shows cards, the “Discover” tab can show tiles or list items
Delve-documentcard
A Delve card, which shows modified date, preview, views, and allows adding to favorites and boards
Delve-documenttile
A tile in the Office365 homepage, showing much less info than the card

Sadly I can not share any comparative screenshots as I can only see this in my work tenant. I am the only user in my tenant so there is nothing to share from others.
But trust me, the Discover tab is an alternative, albeit not a full one, for the Delve Home page.

What’s next for Delve?

My colleague was happy with the alternatives provided.

But when I found this all out I wondered if Delve may be going away as a separate workload as the functionality is now embedded in other, more frequently used, tools. It also has not been included in the recent icon redesign, which may be a clue as well. Would anyone know?
Just as I was writing this post, I found this post from John Liu (in response to a Tweet about Delve from Joanne Klein) who is also wondering about the future of Delve – he has a good idea for its development.

So let’s wait and see if Delve keeps being a separate app, but with added functionality, or will be absorbed into relevant other workloads in Office365…

SharePoint Holmes and the Online Only

sh-onlineonlyThe case

“ I can not open the embedded document” the user told me.
“Ah”, I thought, “I have once solved a case for that”.
“Please ask the site owner to make sure the library opens in the client application” I told the user. “Because embedded documents do not open in the online version“.
I thought that was the end of it, but some time later the site owner contacted me, telling me that the document library always opened in client so he did not understand what I meant.
To be honest, I did not understand it either anymore, so I needed to put on my sleuthing hat.

The investigation

  1. I checked the library and the settings. Yes, the library was set to open in the client.
  2. I selected the document and opened it with Word. No problem.
  3. I asked the user which version of Word he had. A recent client version.
  4. Then I checked his permissions to the site. Somehow or other I always end up checking permissions. The user had Read permissions, as expected.

    sh-onlineonly-sitesettings
    The user was in the Visitors group with Read permissions to the site (In Dutch it is “Lezen”)
  5. I looked at the items with different permissions and noticed that the document library had different permissions from the site. There I saw that the user had been added with View Only, which according to the description means: View pages, items, and documents. Any document that has a server-side file handler can be viewed in the browser but not downloaded. File types that do not have a server-side file handler (cannot be opened in the browser), such as video files, .pdf files, and .png files, can still be downloaded. 

    sh-onlineonly-librarypermissions
    In the Document Library this group has “View Only” permissions.

6.  I gave my colleague the same permissions to the site and checked what happened. Indeed, she could only open documents in the online version with that role.

sh-onlineonly-opening
The user could only open documents in Word Online. No option to use Word Client.

The solution

The site owner had inherited the site and did not know why this permissions set had been given. To be honest, I have never used it so I wonder what people use it for.
I explained the situation and told him that the determining factor was the need to see the embedded document.

  1. If the user had no need for the embedded document, he could leave the permissions as they were.
  2. If the user needed to see the embedded document, he still had two choices:
    – Make the document available in the document library, instead of embedding it, and leave the permissions as they were
    – Give the user Read permissions

Tips:

  • Be aware that people with View Only can also not Copy or Move.

    sh-onlineonly-nocopyormove
    There are no Copy To or Move To options when you have View Only
  • @Site Owners: stick to the standard roles as much as possible
  • @Site Owners: always ask your predecessor for the why if you see any strange things when the old site owner hands over the site to you. (Yes, I know this will not happen, but a support girl can dream 🙂 )
  • @Support people: You will have noticed by now that you should always check
    – Client/Online opening behaviour
    – Classic/Modern settings (they are not an issue here, but have been unexpected causes of issues in other cases)
    – AND permissions

SharePoint Holmes and the Gone Gallery

800px-Northwestern_High_School_Student_Art_GalleryWhile all consultants are writing about Modern Sites, Hub Sites and Communication sites, I am quite certain that a lot of us practitioners are still working with the Classic sites. Looking at “my own” environment this will not change overnight.

(One of the joys of being a practitioner is that you can watch an intranet grow old…and not always gracefully 🙂 )

So here’s another case of Classic SharePoint Investigation.

The case

“I can only add app parts to the page,” the user said. “I am the owner of the site and I would like to add Summary Links, but I can only see the web parts for the document libraries and lists in my site.”

And indeed, when I looked at her page in Edit mode, it looked like this:

SH-GG-WebParts
Although the user had selected the Web Part Gallery, she only saw the App Parts.

 

SH-GG-AppParts
This is what she saw when she selected the App Parts – exactly the same!

 

The investigation

  1. The site permissions were OK – she indeed had the correct permissions to manage the site.
  2. I checked the permissions for the Pages library and Pages – all were inheriting from the parent so that was not the issue.
  3. I logged in as admin (that account has Administrator permissions on all site collections in the tenant) and I saw all web parts. So it looked like another permissions issue.

    SH-GG-CorrectWP
    Same page, different user: I could see the web parts
  4. I asked the owner to which business she belonged. That was Business B. This gave me the clue that I needed.
  5. I checked the site collection – this was a site collection for Business A.
  6. So I checked her permissions on the site collection level – none, as only employees of Business A had access.
  7. To confirm, I checked her permissions for the Web Part Gallery.  Bingo!

The solution

As we are divesting Business B, we have removed all permissions of the Business B people from all site collections of Business A, and vice versa. This means that the Galleries in the Business A site collections are not accessible to employees of Business B. It is an exceptional case that a Business B owner is an owner of a Business A site, but there was a reason for that.

Fortunately the Web Part Gallery had unique permissions, so I added her to the Gallery and then she could do what she needed to do. I did not have to worry about maintenance as her account will be removed in a few months automatically as the system separation takes place. (I may write about that later.)
Frankly, I do not know which permissions a Web Part Gallery should have by default, as I have seen both “inherited” and “unique” while checking some site collections.

This case is probably not very common, but if you ever get incidents where people can not see the web parts when editing a page, please check permissions of the Web Part Gallery at the site collection level. I remember once accidentally removing all permissions at site collection level, and after I had added the groups back, several Galleries were inaccessible as due to unique permissions the groups had not been added back automatically…

SharePoint Holmes and the Survey Surprise

Survey-Detective_Maxwell_on_his_desk_in_the_movie_Until_DeathMost questions I receive about SharePoint surveys are permission issues (it is not extremely intuitive that you need to give all your audience Contribute permissions) and the error message that tells people you can not enter this survey twice.
But this time the issue was different.

The case

The site owner had created a survey in which each item had to be completed by two people. When the first person had entered their part, they would send the link to their entry to the second person, who was supposed to enter the rest.
However, the second person could not open the link and got an error message.
“Sorry, something went wrong. No item exists at [location]. It may have been deleted or renamed by another user”.
When that second person went to the site and opened the survey, they could see that an item had been entered but when they clicked “Show all responses” they received a message that there were no responses.
Confusion all around!

The investigation

  1. I checked the permissions, of course.
    The second person had Contribute permissions to the survey, so that was OK. Everyone could see and edit all items, which is a bit scary, but as this was a controlled process with a limited audience, that could work.
  2. People could enter multiple responses, so that was also not a limitation that could cause this issue.
  3. I checked the survey itself. It had some branching. I completed the first part of the survey and clicked Save and close. My entry was saved.
  4. I went to the survey and saw the item and could open and edit it.
  5. I looked at the 2nd part of the survey, which had many required responses and that gave me some ideas to test…

As it turns out,

  • You are unable to save a straightforward Survey item (with no branches) if it contains questions where you have to provide an answer. We know that, it is the same as with List items.

    Survey-needsmandatoryfields
    This survey can not be saved when the required fields have not been completed.
  • A survey with branching however, will save answers, even if you have not entered all mandatory fields. You will get a message and the item will be saved as “not complete”.
    Survey-setup
    With the yellow-marked question the branching occurs, and there are 2 questions which require a response after that.
    Survey-page1filled
    This is what the first part of the survey looks like. The first person would “Save and Close”.
    Survey-messageforsaving
    “This website reports the following” – you are learning Dutch as you go along 🙂
    Survey-part1saved
    When you Save and Close,  the item will be stored and be visible.

    Survey-1responsenotcompleted
    If you click on “Show all responses” you will see that the item is “not completed”.
  • People can only see the completed items of someone else. As the item is “not complete” because the second part with mandatory questions is not completed,  second person Mystery Guest can not open my item, even though she can see there is an item and she has all the permissions.
    Survey-MysteryGuestsees1item
    Mystery Guest can see there is an item added…

    Survey-NoresponsesforMysteryGuest
    …but when she clicks “Show all responses” she gets the above message.
  • When I removed the “requiredness” of the answers of the 2nd part, the survey was marked as “complete” upon saving, and then the 2nd person could open and edit the 2nd part of the survey.

The solution

I discussed my findings with the site owner and suggested to make the answers in the second part of the survey no longer mandatory. I showed him how to create views in a survey to help getting the second part completed.

That worked for him. Case closed!

New experience for Surveys!

I also saw the Survey in Modern SharePoint. I appreciate the new consistency with other lists, but I can imagine that people will be lost without that well-known look-and-feel. But then, I expect that Forms will make the Survey obsolete soon, anyway.
I wanted to share a screenshot, but things are not very stable yet and I kept getting errors and the Classic experience. As soon as I have captured it, I will share!

7 Risks of Copy To and Move To (in SharePoint Online)

In my earlier post, I explained what happens when you use Copy To and Move To. CopyMove-Risks

I really like using it, but of course there are some risks too, especially because it is very easy to do.
I have already encountered the first casualties and I assume many more will follow.

So here are some things that I think are a tad dangerous:

  1. Even people with only “Read” permissions can Copy your content to a site they have more permissions to, or to their OneDrive. What does this do for “one version of the truth”?
  2. It is now very easy to Copy confidential content to a location with a completely different audience.
  3. People with Contribute or Edit in your site can Move documents to another site and delete them from your site.
    This has been a recent issue with one of my users. He reported that he had lost a large part of his site’s content and did not know what had happened. Fortunately I found his (200+) documents in the Recycle Bin. They had all been deleted by the same person, in a time span of about 5 minutes. I still do not know if that person had really used the Move option, but it is plausible.
  4. There is no way for you, as a site owner, to see if content has been Copied to a different site.
    You can see in the Document Information Pane if people have deleted content. You could also set an Alert for Deleted Items, so you know quickly if an unexpected large number of documents has been deleted and you can ask the deleter if they have Moved content. But for Copy…no option.
  5. As far as I know, there is no option for the site collection admins to see what has happened, except when documents that have been deleted are mentioned in the Document Information Pane or show up in the Recycle Bin. (Please let me know if you have found how to do it – a third-party tool perhaps?)
  6. You can lose metadata and versions if the target contains fewer than the source. With the new versioning settings the latter will probably not cause many issues.
  7. You can break links as I found out recently. I moved some documents around because I wanted to combine some libraries and I had forgotten these were accessed from Promoted Links. Duh! 🙂

How to counteract:

1. Give everyone only the permissions they really need

Making sure every person has the correct permissions is getting more and more important.
With the defaults for sharing and access requests set to give people “Contribute” or “Edit” permissions accidents with Copy or Move are more likely to happen.
Delve, that shows you potentially interesting information that you have access to, makes this part of site ownership even more important!
I often use an extra permissions set called “Contribute without Delete” which means people can Read, Add and Edit but only the Site Owner can delete content. That reduces the likelihood of content disappearing.

2. Inform users how Copy To and Move To work

If your users know how this works, they may be more aware what they are doing. Perhaps this picture helps to convey quickly what happens.

CopyMove-Versions

3. Inform users of the confidentiality of your content

Always make your site’s audience aware of the confidentiality status of your content. Not everyone may realize that some content (such as new brand names, prices or competitor info) may damage your company, should it fall into the wrong hands.
Tell your audience which content should not be shared and copied, and what the consequences could be if they do, both for the company and perhaps even for themselves.

4. Set Alerts for deleted items

You may want to set an Alert for content that is deleted, so you are warned when you see an unexpected large amount of deletions, for instance. As you can not restore the content someone else has deleted, contact your support team as quickly as possible to restore the content.

Of course I am curious to learn which issues you have encountered, and how you have solved those!

10 things to know about Copy to and Move to (in SharePoint Online)

CopyMove-headerOf course you all know a number of ways to move documents from one place of SharePoint to another, such as Open With Explorer*, Content and Structure** and 3rd party tools.

But have you tried the “Copy to” and “Move to” options in SharePoint Online?
(I will use the words Copy and Move throughout this blog as this makes it easier to read…and write)

CopyMove-bar
Copy To and Move To become visible when you select one or more documents

I knew that Copy has been available for some time in document libraries, but only recently I have also discovered Move. So I decided to find out how it works and how I can explain this best to our audience. The Microsoft Help is accurate and helpful, but it does not mention everything.

1. This is only available in document libraries with Modern Experience. 

2. Copy and Move are available for Document, Asset and Picture Libraries.

You can Copy and Move folders or individual documents to other Document Libraries.
You can Copy and Move images from Asset and Picture Libraries, but only to the same Asset or Picture Library or other Document Libraries.
In Pages Libraries, you can only Copy a page and then only to the same Pages Library. This is useful when you want to base a page on an existing one.

CopyMove-Pages
In a Pages library, you can only Copy a page to the same library. No other targets are available.

 

CopyMove-targetoptions
Source and possible target libraries

3. Copy and Move can be done between OneDrive and SharePoint Online and vice versa.

CopyMove-OneDrive
Your OneDrive is always shown as option.

4. Copy and Move can be done between different site collections, unlike “Content and Structure”.

5. What you can do depends on your permissions.

a. To Copy, you will need at least “Add” permissions in the target site.
You will be adding documents, so you will need Contribute, Edit or Full Control or similar.
“Read” permissions to the source site are sufficient in order to be able to Copy content.
b. To Move, you will need at least “Add” permissions in the target site AND “Delete” permissions in the source site, as Move deletes the documents in the source site.

CopyMove-Permissions
The roles you need

 

6. Copy only copies the latest version, Move moves all versions.

This is the same as with Content and Structure, but it does not hurt to mention it again, as this is now available for more users and can have consequences!

CopyMove-Versions
Differences in Copy and Move w.r.t. versions

7. Move keeps the original Created and Modified dates and names.

Copy keeps the original Modified date and Modified By name, but Create date will be now and Created By will be the name of the person who copied. This makes sense, as you are creating a new instance with new Create info.
This can also be slightly confusing, as the Create date can be later than the Modified date.
In the screenshots below, I have used the same Source Library and two different Target Libraries, to show the difference between Copy and Move.
The documents have different dates, people and versions.

First, let us Copy the 3 selected documents

CopyMove-Copy3docs
Version number are 3.0, 2.0 and 5.0, respectively. Different names in Modified By and Created By.

 

This is the result:

CopyMove-3docscopied
All documents have been copied as a new version with the Created date of some minutes ago – while the Modified date is earlier! Created By is me (I did it) while the Modified By is still the same.

 

Now, let’s Move the same 3 documents to a different library:

CopyMove-Move3docs
Now we are moving these same 3 documents

This is the result:

CopyMove-3docsmoved
The original names and dates are in Created By, versions are the same.

 

8. You will receive warning messages in certain scenarios.

a. You Move a document to a target document library that has fewer versions enabled than the source. In this case, document Sharing 9 has 5 versions, the target library 3. You will get a useful warning and the option to stop the process. You do not get this warning when you Copy, as this only copies the latest version.
(This will become less of an issue with the changes in versioning coming up)

CopyMove-VersionWarning
Warning about fewer versions

b. You Move a document to a document library with fewer/different metadata. In this case, I am moving a document that has a Topic column to a target without that. Again, you can Copy it with no warning.

CopyMove-metadatawarning
Warning about different metadata

c. You Copy or Move a documents to a target location that already has a document with the same name.

CopyMove-Titlewarning
You can not Copy or Move when a document or folder with the same name exists in the Target library

d. You Copy or Move a document to/within a document library that has Content Approval, and do you not have sufficient permissions to approve content.
Added April 21, 2019, thanks to this blog by Paul Matthews.

041319_1828_accessdenie2
Not enough permissions to approve new content, in this case.

e. When you Move content, you delete content in the source. When you Move (and therefore delete) many documents in one go, you will receive a warning message. This is very considerate, but please be aware that it may freak some users out!
Added April 21, 2019, thanks to a screenshot from Joanne Klein:

IMG_0178
I think this is a helpful email, because it creates awareness of what you have done. 

9. This functionality is not available for guests.

Guests who want to Copy or Move get an error message, even if they have the correct permissions and see the options. Judging from the error message, the sites shown in the panel are sites you follow and/or have recently visited. As externals have no OneDrive to store their Followed sites, nor Delve to see the recently visited sites, this makes sense.
This may get awkward for long-term trusted external partners, though.

CopyMove-MysteryGuestIssue
Even though the option to Copy or Move is displayed, external users/guests can not do this.

10. The sites that are suggested as targets are based on the Office Graph. 

A good reason to Follow your sites – they show in the targets panel and save you searching. The suggestions are based on the Office Graph and this explains why external guests can not Copy or Move – they have no Office Graph. Thanks to Greg Zelfond for providing me with this info!

What is shown here depends on your Office Graph.

 

My two cents

I am quite happy with this functionality. It is very simple and it will be very useful in case of organizational change or archiving a project.
I now use it all the time when I move instruction and help documentation (that I write using a Word template on my laptop) from my OneDrive to SharePoint. Somehow it feels easier.

However, I would not be me if I did not see some risks. But as this is already quite a long post, I will leave that for next time.
