Getting January sign in issues ?
Recently i’ve been getting SSO sign in issues in Microsoft Teams, Outlook and Remote Desktop App.
Error code: CAA2000C
Server message: User is required to permit SSO.
I’m running Windows 11 and it seems to be caused by: 2024-01 Cumulative Update Preview for Windows 11 Version 23H2 for x64-based Systems (KB5034204)
Uninstall the KB, restart and everthing is back to working again.
