Hey Everyone,
Ran into an issue today that was out of the blue and fun I think would be helpful for some of you. Earlier today a couple of my users were signed into Teams and sat them at a disconnected screen and to sign back in. After relaunching Teams it brought them to a "We Ran Into Trouble 1002" and a "Something Went Wrong 1001(or 1000)" error page. Effectively making them unable to open and even attempt to sign into Teams.
Troubleshooting through this and blowing out the cache in ~/Library/Application\\ Support/Microsoft/Teams/Cache and a restart did not resolve it and there are no Microsoft Teams Identities Cache entries in the Keychain to remove either if you are using either or both Jamf Connect and the Microsoft SSO Extension.
To resolve this I had to delete the Teams Cache folder from the machine, un-scope the MS SSO Extension to the device and after a restart the user is prompted to sign into Teams again without an issue. I believe this is stemming from an issue of users not updating their passwords properly via Jamf Connect or it could be just an issue with Teams itself. The article below on the MS Forums covers the reported problem of Error 1000-1002 and the resolution however if you have the MS SSO extension enabled you will just keep going in circles.
I hope this saves someone some time.
