One sign that OneDrive may be having problems syncing files is if you see it ‘Processing Changes’ for a long period of time, or, if new files or changes from other colleagues are not appearing.
Resetting OneDrive is easy. Open the Run box (Windows Key + R) and enter the following:
%localappdata%\Microsoft\OneDrive\onedrive.exe /reset
Occasionally, you might receive an error that Windows cannot find that path. If so, try the following
C:\Program Files\Microsoft OneDrive\onedrive.exe /reset
C:\Program Files (x86)\Microsoft OneDrive\onedrive.exe /reset
OneDrive will close. Start OneDrive again by searching in the start menu and open.
You will see in the status that OneDrive will start processing changes. This will take a little time depending on how many files you have synced.
Other Useful Tips
Over time, your PC hard drive may start to get full if you sync a large amount of files. Use StorageSense to offload files you haven’t opened periodically, as well as clear up your downloads folder and recycle bin:
