Thanks for the effort Zakhary but that doesn't help.

1. I deleted ALL rules (as stated before).
2. We are in a exchange/client enviironment and we have email groups, not
newsgroups. It is not a certain email group but a very random problem with
any group. (as stated before)
3. I gave rather specific details to this problem not broad at all.

What rules have you deleted. I don't use 2007, but other than the graphics,
navigation, and contact system settings, it generally operates the same.
Based on your information, what comes to my mind is creating a rule that
would permanently delete duplicate messages. You mention that the messages
are from particular newsgroups or other groups that they are members of. If
that is the case and their membership exists on both email accounts, I would
either remove their membership on one of the accounts or apply a rule that
permanently deletes messages coming from the newsgroup address to a
particular account.

This is the best recommendation I can offer based on the relativley broad
details you have provided.

I have some users that are running Outlook 2007 that are having a problem
when we add a additional mailbox to their setup (Tools-Account
Settings-Change-More Settings-Add). The additional mailbox is fine with no
problems. But what happens is their main mailbox starts receiving duplicate
emails. This only happens with users that keep their mail in a PST instead of
the server mailbox. Normally it is an email that is sent to them because they
are a member of an email group (any group not a certain one). When they start
receiving duplicate emails they will receive 100's-1,000's if they don't
catch it. Once this happens the only way to stop it is to close Outlook, log
into OWA and delete the email, then open Outlook again (and clean up all the
duplicates).This has been an on going problem here for months with some users.

I have tried the following:
1. Delete all rules being processed.
2. Delete and recreate Outlook Profile.
3. Delete and recreate Windows Network Profile.

The only thing that I have found that fixes this is removing the additional
mailbox or moving their default email location to the server instead of a PST.

Thanks for any help that anyone can provide. I really need to get this fixed.
