The OneDrive troubleshooter is a tool that can find and automatically fix these common problems with OneDrive in Windows 8.1 and Windows RT 8.1:
OneDrive doesn't appear in the left pane in File Explorer.
Even though you're connected to the Internet, you can't connect to OneDrive.
Some of your OneDrive files or folders are missing on your PC.
Some files or folders won't upload from your PC to OneDrive.
The OneDrive icon doesn't appear in the notification area, at the far right of the taskbar. (In Task Manager, the sync engine process doesn't appear.)
You see the message "You don't have permission to save to this location. Contact the administrator to obtain permission."
Running the troubleshooter.
You might be asked for an admin password or to confirm your choice.
When you run the troubleshooter, you'll see these two buttons:
Send diagnostic information to Microsoft. Choose this button to save a log file to your desktop that you can later provide to Microsoft support.
Reset OneDrive. Choosing this button will fix most problems, but it resyncs all your files, so it might take a while if you have a lot of files. Resetting OneDrive doesn't change any OneDrive settings that you've selected.
