I thought I had this problem licked but it reappeared today. I have tried stopping the internet mail service and deleting the queue.dat file. It seemed to work for a day and now I'm back to the original problem. I'm running Exchange 5.5 sp4 on NT4.0 sp6a. Recently I have started getting a few users sporadically receiving the same email over and over. Each user is getting it from a different sender, all from outside the company. There doesn't seem to be a particular pattern. The user will recieve the email and reply to it, delete it, whatever, and then get it again an hour, 2 hours, a day later. Sometimes the user will get 20 or 30 copies of the same email. I have checked MS site, this site with no luck. Am also running Trend Micro on same box. The weirdest part is even though I am filtering some of these messages at the server through Trend Micro they still keep coming through, which leads me to believe that the problem is with my Exchange server. Any ideas?

It could be a corrupted POP3UIDL.DBX file. Try deleting/renaming it to see if that helps.

If your queue.dat file periodically stops working, I'd try running a chkdsk and/or integrity check (if a RAID set) on the disk(s).

How would I know if the queue.dat file periodically stops working? I never seem to get any interruptions in mail service.

The queue.dat file tracks messages processed by the IMS and their status. When it stops working properly, one symptom is that users will get multiple copies of the same message because queue.dat doesn't update to reflect message delivery.

The first poster's recommendation (removing POP3UIDL.DBX) might apply if your clients run Outlook Express. The POP3UIDL.DBX file is on the client side, not the server.

I have already deleted the queue.dat twice and that doesn't seem to have helped and the clients are running Outlook 2000 not Express. The 2 people affected each get emails at specific intervals, one every hour and 15 minutes and the other every 4 hours.

This is a long shoot since the deleting the dat file did not work. Have you tried running eseutil and isinteg
isinteg Article ID: Q183400
isinteg Article ID: Q170091

There should be a readme file located on your exchange server on how to run both Utilities.
Sorry the last fix did not fix your problem. I thought it would. Hopes this helps. Good Luck!
