Okay chaps and chappesses - 500 pointer here...
We have a problem with messages coming into our Exchange Server. Basically, the messages are stuck in the SMTP queue.
This only seems to be happening to certain users, but I've not managed to find out where the thing to "unstick" these users is.
A message will come into the server, I can see it listed under "Exchange System Manager", but if you list the properties of the message queue it says something like
17:10 SMTP Message queued for local delivery
17:10 SMTP Message delivered locally to email@example.com
17:10 SMTP Message scheduled to retry local delivery
17:11 SMTP Message delivered locally to firstname.lastname@example.org
17:11 SMTP Message scheduled to retry local delivery
The mailboxes of these people appear to be okay, but I'm just not certain if there is something I am missing. Any advise on what I should be checking for would be most appreciated.
