I have an email with attachments in my inbox that is tagged as having been forwarded on 5/5/09; there is no entry in my Sent Items folder for the email having been sent; there is no entry for the email in either my Draft or Deleted Items folders; there is no entry for the email having been sent from the Exchange Server using the Message Tracking system.
How can an email be tagged as having been forwarded without any trace of it having been sent?
