A user whos laptop was joined to Azure AD was suddenly not being able to connect to Teams due to caa70004 error and Onedrive was bringing up 0x8004de40. WebApp worked fine , password had not been reset.
Rejoining the PC Azure AD didn’t resolve , and that Windows Profile could not join to any other Microsoft Account. Signing into the PC with a Local Username and password it could open and sign into Microsoft Apps
Our organization whitelists the 2fa prompt on trusted IP’s , so we changed the machine to connect to a non trusted IP 4g Hot Spot , which allowed the user to enter in the 2fa code and re-sign the Authentication Token
