We have an on-premise RDS Solution that uses an RD Gateway for remote users, along with MFA (previously PhoneFactor) and all works well. We've recently tried to set a One Time Bypass in MFA for a few users but it never seems to work. On further investigation it seems that MS state "unless your MFA is associated with an Azure Directory, this feature won't be available".
I'm trying to find out if this is true and, if so, can we associated our MFA subscription with an Azure Directory without causing any issues for the live users?
Cheers for now
