duplicate emails -- posted by a relative newbie

I'm having the same problem with duplicate emails that have been described
in many of the below posts and am baffled as to what to do..... I have
outlook 03, and in the past few months after upgrading from a previous
version of outlook, I
have been getting some duplicates. Now it's increased to about 3/4 of all
the emails I receive -- What happens is when the email is downloaded, it
downloads several copies of the same email -- they all have the same time
sent -- when I go to mail2web.com to view emails, there's only one copy of
each.

I only have one email account on this computer -- and I have checked to make
sure that copies aren't being left on the server.

I looked at the answers posted thus far and don't quite how to stop all of
the
rules I've set up from sorting into folders from working -- do I go into
the rules and stop each one individually, or is there a quicker way?

If that works, is there ever a way to have rules applied as I really would
like to have my rules in place for sorting incoming email?

If that doesn't work... any other ideas that I've missed?

thanks,

Paul
