I have seen numerous postings on this group concerning duplicate messages
being received using Outlook 2003.  I also have this problem and have done
all of those things that have been suggested.  Still, the problem persists.
I am getting very frustrated with Outlook and the need to delete three
quarters of my messages since they are duplicates.  Yes, now I am getting
three and four copies of some messages.

In an attempt to help you help me, the following is what I see and what I
have done so far.
    1.  I get duplicates at the time of the download from the mail servers.
In other words, I can check my earthlink account via webmail and there
might be one message there.  When I download that message via Outlook, I
will get anywhere from 2 to 4 copies of that message.  After downloading
with Outlook, a check of my earthlink account will show the mail box empty.
This is the same with my other email account.
    2.  Duplicate messages come from two different ISPs.  One is my local ISP
that allows me access to the internet via DSL connection.  The other is a
volunteer group earthlink account.  Not all messages from eather account
come in multiples, just some.  Those that do are always the same senders.
    3.  I do NOT have the "Leave messages on the server" block checked for
either account.
    4.  I have created a NEW profile.  This did not help.  I did not copy my
existing profile, but created one from scratch.
    5.  I have created a .PRF file using the Custom Installation Wizard.  No
help here either.
    6.  I have run the Detect and Repair option of Outlook.  No help.
    7.  I have checked with the customer services departments of both ISPs.
They both indicate that the problem is with Outlook, not with them.

I do not want a third-party add on that probably will not fix the problem.
I want Microsoft to fix it.  After all, it is their program.

Any help that this group, especially the MVPs, would be appreciated.
