OneDrive Syncing Duplicate Files

I have a user who has known folders (Desktop,Documents, and Photos) redirected to OneDrive, so it's syncing all those items to a folder into OneDrive. The issue is that everytime they restart, it duplicates every single item and tags it as "-Copy". Screenshot attached below:

I've already re-installing, resetting OneDrive. Thanks in advance.

I am not sure what you mean by redirecting and that could be the issue.

Instead, instruct OneDrive to sync specified folders https://support.microsoft.com/en-us/office/choose-which-onedrive-folders-to-sync-to-your-computer-98b8b011-8b94-419b-aa95-a14ff2415e85

Hi Scott,

Thanks for the response. I guess redirection is the wrong word to use here. The article you linked is exactly the config I am talking about, known folders syncing to OneDrive.

This is not straightforward to diagnose as there can be multiple reasons. The idea of multiple profiles that Jazz brings up is a good one.  With Microsoft, it is easy to get logged in multiple ways with different accounts. Even M365 has business vs personal.  Often times the user does not realize they have multiple accounts logged in.  Making sure the user profile that is logged into windows, the browser,MS office apps and OneDrive match up.

Also dumping in a large amount of data I found to be troublesome with OneDrive.

Another problematic issue is having multiple syncs on the same local folder. If you have OneDrive and Dropbox or Google Drive for instance syncing the same local folder, the syncing process of one can cause the other to think there is a new file.

If there is another 2nd device that is syncing to the same account, you will want to check for the same issues as the first device.

Hi Scott and Jazz, thank you very much for the responses. We were able to figure out the issue, we have another program that also does some registry/GPO management among other things and we found an old rule in there a previous admin had made that was causing the duplicate sync in OneDrive. Once we removed that the duplicate sync issue disappeared.

Thanks again, the responses were still very useful.
