A Microsoft file hosting and synchronization service.
Try this order for OneDrive sync errors on a PC:
- Check whether OneDrive is running.
- Look for the white or blue OneDrive cloud icon in the taskbar notification area.
- If the icon is missing, it may be moved into Show hidden icons, or OneDrive may not be running.
- Open the sync error details.
- Right-click the OneDrive icon and review the current sync problem.
- If available, use View sync problems to see which files or folders are failing.
- Check common causes.
- If the OneDrive account is full or nearly full, new files will not upload or sync.
- If a file is open in another app, save and close it, then try again.
- If the folder is not selected for syncing, open OneDrive Settings > Choose Folders and make sure the needed folder is selected.
- Stop and re-establish sync.
- Right-click the OneDrive icon in the notification area.
- Select Stop syncing a folder…
- Choose the affected folder, select Stop syncing, then confirm.
- Start syncing the library again.
- This disconnects the folder from the library but keeps files in both the local folder and the library.
- Do not rename the synced folder after sync is established, because that breaks the sync relationship.
- If issues continue, try unlinking and relinking the account.
- This is listed as a next step when general sync troubleshooting does not resolve the problem.
- If using the older OneDrive for work or school sync app (groove.exe), use Repair.
- Right-click the OneDrive menu icon in the taskbar notification area.
- Select Repair, then select Repair again in the dialog.
- Do not restart the PC while Repair is running.
- This applies only to the previous OneDrive for work or school sync app, not the newer sync app.
- Review file restrictions if only certain files fail.
- Sync can stop because of unsupported file names, file types, size, or other restrictions and limitations.
If the problem is specifically a large number of errors, stopping sync and syncing again is the recommended reset path because it gets fresh data.
