hi shaun,
the issue could be caused because onedrive for business lost the necessary credential to connect to your office 365 sharepoint directory.
could you have a shot at the below steps? we will move forward based on the results.
- stop the syncs in onedrive for business sync client.
- exit the onedrive for business sync client and all other office apps.
- open an office desktop app such as word > file > account > under user information, sign out all you existing accounts > exit word.
- go to control panel > user accounts > credential manager > windows credentials > under generic credentials, remove all your office 365 credentials.
- press win+r > input regedit > ok to run the registry editor.
- navigate to and delete the following key and all of its subkeys from the registry.
hkey_current_user\software\microsoft\office\16.0\common\identity
- open word > file > account > under user information > sign in with your office 365 account.
- open the sync client to start a sync.
you can post back at any time and we will follow up on your case.
best regards,
frank
