Exchange, GAL, AD, disabled users, several questions
Our environment is Windows Server 2012 R2 domain @ 2008 DFL/FFL with Exchange 2013.
When we disable a user in AD, email does not bounce and I would expect it to. I think it's because we are at 2008 DFL/FFL. To test this, I logged into another domain I manage that is 2012 R2 DFL/FFL and tested. When I disable users there, the mail bounces.
In my 2008 DFL/FFL I have to manually disable the mailbox before mail bounces.
So, my question is, is something broken? In a 2008 DFL/FFL domain with Exchange 2013, should mail bounce when a user is disabled in AD? Must I manually disable the mailbox as well? Why? This seems counter intuitive as I clearly recall disabling a user in AD killed access to everything in earlier versions of Windows.
