Cannot login to O365 when in Skype for Business 2019 Control Panel

EricK 1 Reputation point


This is new tenant and new Skype for Business 2019 setup. When I try to set up hybrid using Control Panel, I cannot login. I think it could be MFA, but I am not sure. Here is the error that I have. Can someone help me with this?


Thank you.

    @EricK ,

    In Azure Active Directory, if you do an initial login in one location, and then login from another location, there are conditions on the AD that flag this as "risky activity".

    For your account there is a "moved to a new location" flag that can get set, automatically triggering the need for MFA. If you do face this, check the conditional access locations in Azure and see if your AAD admin can clear the flag.

    For more details, please refer to this article:
