Teams desktop client macOS authentication prompt
jjgage Okay, I think I may have figured out what's going on in our tenant. I logged into Teams in the browser with the Developer console open and I'm seeing errors like this one:
AUTHADAL: Attempting to handle auth response: error:AADSTS500014: The service principal for resource 'https://*.microsoftstream.com' is disabled. This indicate that a subscription within the tenant has lapsed, or that the administrator for this tenant has disabled the application, preventing tokens from being issued for it., resource:https://*.microsoftstream.com, error mapped to action:resourceDisabled
We have Microsoft Support working on our Stream tenant and as part of that process, we were required to disable the application from the Enterprise Applications blade of the Azure AD admin center. I suspect this may be the cause of the repeated authentication prompts. Strange that it's only affecting Teams on Mac. 🤷
jjgage I'm also seeing issues with Teams on macOS repeatedly displaying an authentication prompt. In my case, it occurs whenever I switch to the Calendar tab. I checked the Exchange Online service principal and it was already enabled.
Ryan Steele Are your users using EXO for mail or still On-Prem? And are you Hybrid or Azure only?
jjgage We are in Exchange Hybrid with Exchange 2013 on-premises, and the affected users I'm aware of are all in EXO (previously on-prem and migrated).
Ryan Steele presume modern auth enabled across the board? EXO, Skype (even if not using), Hybrid?
