Customer had a scanner sending fax information as email to a resource mailbox. They had the address incorrect on the scanner so there was no mailbox to deliver to. Does Exchange 2007 store those non-deliverable emails somewhere that I can recover them? Using the message tracking tool I believe I have the message IDs but I have no idea how to recover them. The fax apparently contains some sensitive information and they don't want to ask the customer to resend it. This is an Exchange 2007 SP3 Server running on Small Business Server 2008.
