Hi, help me please.
I have 2 Domain Controllers (AD1, AD2, AD1 has all FSMO roles, AD2 only global catalog + role witness for DAG ) and 2 Exchange 2013 CU1 (EX1, EX2) servers (all mail roles in each + DAG). It's one Domain Site and one Network Sub-net. AD1 and EX1 are in office, AD2 and EX2 are in data-center.
All work is good.
If I will lose connect with office, my users can't send email over 587 port. There have authentication error on client, mail client require a password and return an error. But, users were used protocol HTTP-over-RPC worked without of problem.
How can I fix the problem for Frontend connector on 587 port ?
