I have a mail.que on Exchange 2007 SP1 that keeps growing (2Gb) overnight even when send/receive connectors are disabled. I have stopped the transport service, deleted the mail que and restarted but the problem persists.
if left, the server disables mail traffic based on Back Pressure Buckets exceeding the configured limits (which are std). Exchange has been performing fine until 36hrs ago.
No messages appear in the que.
Most solutions call for the mail que to be deleted but this has not solved my problem. Any help would greatly be appreciated.
