I am not sure what you mean by redirecting and that could be the issue.<br><br>Instead, instruct OneDrive to sync specified folders&nbsp;<a href="https://support.microsoft.com/en-us/office/choose-which-onedrive-folders-to-sync-to-your-computer-98b8b011-8b94-419b-aa95-a14ff2415e85" rel="ugc">https://support.microsoft.com/en-us/office/choose-which-onedrive-folders-to-sync-to-your-computer-98b8b011-8b94-419b-aa95-a14ff2415e85</a>

Hi Scott,<br><br>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. &nbsp;With Microsoft, it is easy to get logged in multiple ways with different accounts. Even M365 has business vs personal. &nbsp;Often times the user does not realize they have multiple accounts logged in. &nbsp;Making sure the user profile that is logged into windows, the browser,MS office apps and OneDrive match up.<br><br><a href="https://support.microsoft.com/en-us/topic/duplicate-files-in-onedrive-fd47ce5e-8dd0-465e-9e3a-461e1a3cf613" rel="ugc">https://support.microsoft.com/en-us/topic/duplicate-files-in-onedrive-fd47ce5e-8dd0-465e-9e3a-461e1a3cf613</a><br><br>Also dumping in a large amount of data I found to be troublesome with OneDrive.<br><br>Another problematic issue is having multiple syncs on the same local folder.

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.<br><br>Thanks again, the responses were still very useful.

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.

OneDrive Syncing Duplicate Files

Microsoft OneDrive (formerly SkyDrive) is a file hosting service and synchronization service operated by Microsoft as part of its web version of Office. First launched in August 2007, OneDrive allows users to store files and personal data like Windows settings or BitLocker recovery keys in the cloud, share files, and sync files across Android, Windows Phone, and iOS mobile devices, Windows and macOS computers, and the Xbox 360, Xbox One, and Xbox Series X and S consoles. Users can upload Microsoft Office documents to OneDrive.

Office 365 is a group of software plus services subscriptions that provides productivity software and related services to its subscribers. Office 365 allows the use of Microsoft Office apps on Windows and OS X, provides storage space on Microsoft's cloud storage service OneDrive, and grants 60 Skype minutes per month. Office 365 includes e-mail and social networking services through hosted versions of Exchange Server, Skype for Business Server, SharePoint and Office Online, integration with Yammer, as well as access to the Office software. All of Office 365's components can be managed and configured through an online portal; users can be added manually, imported from a CSV file, or Office 365 can be set up for single sign-on with a local Active Directory using Active Directory Federation Services.
