A client with SBS2003 uses POP3 connectors to check individual mailboxes at their ISP, and then messages are put into their Exchange mailbox. One connector was correctly set to pickup her mail at the ISP, and was configured to put it into a User Mailbox. Unfortunately, no Exchange mailbox was specified in the connector. Now that I fixed that she's receiving new emails, but none from the period during the misconfiguration. I'm under the impression that her senders did not receive bounce or delayed delivery messages.
Where are the missing emails, and can they be captured?
