Multiple copies of emails

[Michael Lynch]

I have a user who, after I switched him over from Internet
access to corporate access to our exchange server, began,
intermittently, recieving massively multiple copies of his
emails. This morning he had 1137 new emails! Can anyone
tell me what's going on? Thanks.

Not without some details.

I am having similar problems with 3 different clients that
are using MS Outlook XP. Here are the details.

Client#1

Windows XP Home Edition with all of the latest critical
updates and service packs.
MS Office XP with SP1 and MS Outlook Updates
Norton Antivirus Corporate Edition 7.6
Set to leave a copy of messages on server for 5 days

User will receive up to 200 copies of a single email. The
duplicate emails almost always seem to be pornographic
spam.

(I implemented SpamArrest for this client and that has put
a stop to the porno spam. As far as I know, he is not
having the problem now.)

Client#2

Windows XP Home Edition with all of the latest critical
updates and service packs.
MS Office XP with SP1 and MS Outlook Updates
Trend Micro Antivirus as part of the Ontrack System Suite
Mail is deleted from the server after download

User will receive up to 20 copies of a message. Messages
may or may not have attachments.
User signs on to webmail to delete the message from his
mailbox once he starts to receive the duplicate.

Client#3

Windows XP Home Edition with all of the latest critical
updates and service packs.
MS Office XP with SP1 and MS Outlook Updates
Norton Antivirus 2003

User has just started receiving intermittent duplicates.


All three of these users are receiving there email from
different POP servers. None of them had this problem when
using MS Outlook 2000 or Outlook Express 6.0

I saw several posts about this problem on
groups.google.com, none had a good resolution.

I have checked the following.

1) I am not checking two POP accounts on the same server
2) It happens whether or not we leave copies of the
messages on the server
3 We are not trying to download mail from Exchange and put
it into a PST.

Any suggestions?
