Using Exchange 2003 with latest updates on 2003 network & XP SP2 OS with Office 2003 Professional. Only one user affected. He is unale to receive legitimate emails from clients but gets spam. We use Sybari for SPAM filtering & legit messages are not in quarantined status. I did a repair in Office with no change. I did an uninstall then reinstall with no change. In Message Tracking Center the messages post as being delivered but nothing in OWA or Outlook. Any ideas?
