I am using Exchange hybrid agent and configuring modern hybrid.
I know that hybrid modern authentication is not supported.
I do know what is modern authentication but what is hybrid modern authentication?
Can users migrated to Exchange Online (EXO) use MFA conditional access policy and for me to configure block legacy authentication conditional access policy?
I know users still on on-premise Exchange (EXCH) will not have modern authentication.
Or does it mean that all users whether they are on EXO or EXCH cannot use modern authentication?
