How To Fix One Drive for Business Sync Issues

A customer recently had an issue with syncing their SharePoint Online library with One-Drive for Business.  Some of the files were syncing properly, but some were throwing errors and displaying a red X.  Most of the time sync errors are caused by invalid characters or a bad file name, but this one wasn't the case.  Running repair didnt work, so I went in and manually cleared out all of the One Drive cache files and reconfigured the sync library.

Here's how to do that:

  1. Close all your Office processes like groove.exe, msouc.exe,  msosync.exe, etc
  2. Browse to “C:\Users\%username%\AppData\Local\Microsoft\Office\Spw” and delete all the content.
  3. Go to “C:\Users\%username%\AppData\Local\Microsoft\Office\15.0\OfficeFileCache” and also delete all content from this folder.
  4. After deleted everything,  start OneDrive again (using “C:\Program Files\Microsoft Office\Office15\GROOVE.EXE“)
  5. Configure the sync library again
Even Microsoft support couldnt provide this information to me, so hopefully this help you if you ever have a sync issue that you just cannot fix.
