I need some serious help here guys. One user keeps getting his mail resent. I dont know from where even when his pc is not switched on. All the mail he sent on thursday keeps getting resent. The same messages without any alterations. The user is on Outlook 2000 and the server is Exchange 5.5 I have removed and reinstalled my exchange to no avail. I have also checked for viruses on the guy's pc but nothing. And I have also changed the user's pst file. I check in the guys's outlook under sent items but its not showing the subsequent resends. ANy bright ideas out there.
