Strange Occurrance: Message Gets Sent After Being Deleted
Have a customer who sent a meeting invite as a delegate to their manager. They saw the message was still caught in the Outbox after some time. They delete the message in the Outbox. On another day...
The Outbox folder is used "locally", copying messages will happen only after they have been sent successfully. Do check for any rules involved, as the message trace results seems to be clear on that (including hidden rules via MFMAPI, if no match is found by examining the "regular" rules).
As for the actual "stuck in Outbox" issue, there can be a variety of reasons, ranging from bad network to large Outlook profiles to whatnot. The topic is covered extensively online, do a search.
