OneDrive icons will be stuck in a continuous upload fashion, even though everything has been synced. This is usually caused by documents being uploaded on exit in Office applications.
Close the OneDrive system tray icon on your taskbar.
Open Task Manager and kill any of the following:
1 2 3 4 5 6
groove.exe msosync.exe msouc.exe winword.exe excel.exe powerpnt.exe
Start OneDrive back up and go to Settings => Uncheck ‘Use office to work on files..’
- I use OneDrive as a backup solution with Office365 and never have anyone but me using my documents so I don’t use this option. Obviously if you want that ability, you can disregard this fix.
