Microsoft Teams Error Code 0xcaa80000
I found that deleting the token binding key had resolved the issues for a number of people in Google searches that I did. Only thing is when I deleted the token key I logged into the Teams app and it error'd again. Then as part of a fiddler trace I was doing I kept trying to connect a few times with Teams one after the other and finally the ADFS page popped up to enter the users username and password and it signed in! Unsure if deleting the binding key fixed the issue or not!

Same here with attempting to login to Teams (free, classic). Is the Crypto folder only available for paying subscribers?
Also related to password changes: https://www.reddit.com/r/sysadmin/comments/166kcf0/unable_to_login_to_outlookteams_after_password/
As this older personal issue (ew! tech community link tags are broken with Your post contains invalid HTML. )
https://techcommunity.microsoft.com/discussions/microsoftteams/ms-teams-free-account-types/3716415
was yet unresolved, the thing to do then was to log out of Teams (free, classic) because the email address for the MS personal account in use was changed. Somehow, a whole bunch of problems with this setup remain in situ, unfortunately.
We'll get there! 😀
Ah, that was with the personal account, things are explained a bit better after attempting to login with the work account - see here:

Think the admin might have disabled it some time back, and Humpty Dumpty will not be rejoin ing the Team!
