I updated all our PCS to the latest version of OneDrive. Today, again Microsoft App are telling me our credentails are expired if I want to upload "this" document. Onedrive is working ok however. I cleared credentials in control panel reboot and reboot and reboot and OneDrive doesn't work now.
I uninstalled OneDrive, reboot, installed it again, enter email address and it gave me 1001 error. Rebooted again, OneDrive is OK now but I have to resync Sharepoint folder. I'm doing it right now, but now I look at office applications and I have the same exclamation mark next to the name. So I'm back to square one when I originally started lol. Ok, after opening the file and closed 2 more times, it now seems to be ok. But is that really a solution?
