Logging into teams, I now get the message (freely translated from Norwegian): "Modern authorization did not work here, but you can still log on. Status code is 2:300."
-I'm using Microsoft Teams app on MacOS
-Multi-factor authentication is turned on
-When I exit the error message, I am able to login to the Teams app
-This app was working fine since last year without any error messages popping out
-I encountered this error message just today
-When I restart the teams app, it does not prompt me for my credentials anymore but I still get the same error message
-I don't use ADFS, my tenant is "in-cloud" only
Hi Test Tenant! :)
According to this article, "Modern Auth fails in Teams" this is the answer (also when You do not use ADFS) "Active Directory Federation Services prompt=login parameter support".
Hope this helps!
