exchange 2007 & AD: account disabling and expiration
i’m not sure if this has always been the behavior, but this is how things currently function in our environment.
user’s AD account disabled:
can still use OWA
can not login to endpoints/access AD resources
user’s AD account expired:
can still use OWA
can not login to endpoints/access AD resources
exchange mailbox disabled:
cannot access OWA
mailbox disconnected and marked for deletion
