salihzett I'd recommend:
- right-click on the OneDrive app in your Applications folder
- click Show Package Contents
- open Contents > Resources
- double-click on ResetOneDriveAppStandalone.command
- wait for the Terminal window to say "Process completed" then close Terminal
- open OneDrive and go through the sign-in wizard (you should get options to choose a new location or the location from before you reset OneDrive, what you choose as your OneDrive location is up to you)
Disclaimer: This will remove any OneDrive policies/preferences that you have configured for the app and you will have to put those back using whatever method you used initially (custom plists or manually in the App UI). I would just remove the OneDrive app and cache/container locations from the OS and re-install for good measure.
