|Sign in loops or fails for Teams Phones.|You can't sign in or the sign-in continually loops when both the MFA and the Terms of Use (ToU) Conditional Access (CA) policies are used. |The combination of MFA CA and ToU CA isn't supported. You should exclude it from being used. <br><br> To avoid the sign-in error, ensure that only the MFA CA or only the Mobile Device Management (MDM) CA is used. When only the MFA CA is used, make sure that it's enabled in Device Registration Services (DRS).
