Hi,
I had installed the OneDrive app on my mac and synced all of my files to the cloud. It had worked seamlessly until today, October 17, when I logged into my mac and it asked me to log in to my OneDrive account. However, the "Your OneDrive has not been setup, please contact your IT department for help" error popped up. I tried reinstalling the app and several fixes Microsoft has provided for this same error in other threads (resetting Keychain Access, for instance), and none of them have worked. I can still access the OneDrive web portal, upload and download files, with no issues. However, I can no longer sync my computer files since the app stopped working. I have a school account from University. Here's a screenshot.
