Sometimes One drive has problems syncing and may be running in circles trying to sync a few hundred files, but the number never goes down. 

When this happens, you can try resetting the One Drive sync and it should fix it up.

To reset the OneDrive desktop sync app in Windows

  1. Open a Run dialog by pressing Windows key  Press the Windows key  and R.

  2. Copy this and paste it into the dialog window then press OK

    %localappdata%\Microsoft\OneDrive\onedrive.exe /reset 

    If you see a "Windows cannot find..." message, copy and paste this instead, then press OK.

    C:\Program Files (x86)\Microsoft OneDrive\onedrive.exe /reset

  3. Manually restart OneDrive by going to Start  Press the Windows key , type OneDrive in the search box, and then click on the OneDrive desktop app.

Notes: 

  • Resetting OneDrive disconnects all your existing sync connections (including personal OneDrive and OneDrive for work or school if set up). You won't lose files or data by resetting OneDrive on your computer.

  • If you had chosen to sync only some folders before the reset, you will need to do that again once sync has completed. Read Choose which OneDrive folders to sync to your computer for more information.

  • You will need to complete this for your personal OneDrive and OneDrive for work or school.
