We're running Outlook 2003 on Exchange Server 2007, Windows Server 2003. I recently have encountered a problem where emails to one internal user (User A) have been delayed. The most recent example is that User B sent an email to 2 recipients, one external and the previously mentioned internal user (User A) on 11/05/08. The external user received and replied to the email the same day. User A just received the same email around 7:30am this morning (11/13/08), but date-stamped as if User B had just sent it this morning.
I checked Message Tracking and Exchange says the email was delivered to User A on the day it was sent. It just didn't show up in his inbox until a week later. Any thoughts on where to look from here? (User A is our company CEO, naturally.)
