Hi,

I was in contact with Microsoft for over a year, and they finally confirmed it's a bug. a fix is on the way. The following workaround has proven to be successful:

 

Message from support team:

The Windows team has identified a bug on their end that occurs when numerous user sessions accumulate over time leading to these performance delays.

While the OneDrive fix is rolling out, admins on the AVD / VDI machines can manually clean up the sync roots that have accumulated over time, by deleting the child keys under:

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\SyncRootManager\". 

Note: We recommend that users are logged off of any active user sessions before this cleanup or that the host is rebooted after the cleanup to ensure that OneDrive correctly re-registers with Windows

 

I hope this will serve as a solution until the fix is released by the end of the year.

 

Best,
Franco

Did you test this solution?

I test this solution and it breaks a lot of things...

    Hello,


    We did test this yet and are now implementing this for the end-user. I cannot imagine problems in removing the subkeys because we often apply a new AVD image to the environment and then this key is also empty. But what do you see for problems?

      Environment of 4 AVD-servers with FSLogix profiles. FSLogix is on the latest version. All Windows Updates are installed. Operating System is Windows 11 23H2.

      After I made a backup of the regkey I removed the subkeys. No users were logged in.

      After logging in with an useraccount the sync of multiple applications didn't work anymore. Even after a reboot of the server. I restored the regkey and it starts working again.

      The only workaround that I found working is to temporary change the permission of the regkey HKEY_CLASSES_ROOT\PackagedCom\Package\Microsoft.OneDriveSync... and reverse this change. Doesn't matter which one.

      After OneDrive immediatelly works like a charm. But after every new OneDriveSync version the problem reoccurs. OneDriveSync updates are installed very often and not on a specific day or time. I think of making a script to change the permission of this regkey; but is has to be scheduled to do a check and remediate every minute or so.

       

      Can you give me more information about the environment you manage, is it the same?
