Office 365 Outlook MRU Roaming

Question

Dear all,

if you create a new email and click on add attachment you get a list of mru objects. Some of them are roamed from other devices with the same user.

Is there documentation on the mechanism that composes that mru? And possibilities to filter that mru list?

In office 2013 there was "Office Anywhere", that was responsible for mru roaming according to:
https://learn.microsoft.com/en-us/previous-versions/office/office-2013-resource-kit/jj733593(v=office.15)?redirectedfrom=MSDN

You could disable roaming by setting the following key:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\15.0\Common\Roaming\RoamingSettingsDisabled

But according to this:
https://learn.microsoft.com/en-us/office/troubleshoot/administration/cant-open-files-most-recently-used-list
documents this key has bee replaced with:
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Internet or HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Common\Internet\UseOnlineContent
in office 365

Does UseOnlineContent have unintended side effects? How can I just disable MRU roaming?

best regards,

Hi @enigyma,

Welcome to our forum.

Tried some research but have not found any Official document which explained the MRU Roaming in detail. However, the article Disable or limit the Recent Items list in the Attach File menu I found on the Internet should be helpful to your issue I think. (Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.)

As this article mentioned, you can’t directly filter this list but you can control how many items are being shown by setting a MaxAttachmentMenuItems Registry value. You can also set this value to 0 to disable the Recent Items list completely.
Key: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\Mail
Value name: MaxAttachmentMenuItems
Value type: REG_DWORD
Value: 0

About the UseOnlineContent registry key, issues or errors like this document mentioned might happen due to this registry key. For your reference: (This feature has been disabled by your administrator) error in Microsoft Office.

Hope this can be helpful.
