Microsoft teams код ошибки caa301f4

Having an issue with users being unable to log into the Microsoft Teams desktop app on Windows 10 Machines. In all instances, the users are prompted to log into teams, and immediately receive the error message «We’re sorry—we’ve run into an issue. Restart If that doesn’t work, try signing out and back in. desktop-… Error code — caa301f4″ There’s a more permanent way to sign in to Microsoft Teams. If you’re having trouble completing the process, talk to your IT admin.» Workstations are up to date, uninstalling and reinstalling the app has the same results. Anyone run into this before or have a solution to it?

UPDATE :: So far I have found two «fixes» to the issue for my users. The first is to completely remove the app via uninstall, then removing the residual files in the app data local and roaming locations. Then I check the users account settings and verify if their email account, that is associated with their O365 work accounts, has been added in the Access work or School section, or the Email & Accounts section. If it’s not in the Email & Accounts section I add their account here as an Office 365 Exchange account. Then re-install Teams and I was able to log in without any issues. For the users who already had their email in the Access Work or School and Email & accounts section all I had to do was change the Teams app compatibility settings to run in Windows 7 compatibility mode. Not exactly sure why these have been fixing the issue but these have resolved the issue for 10 of 10 impacted users today. I still have a couple other users to get to today but so far these have been 100% successful in removing the caa301f4 error.
