I have a pop3 account which is linked to a web mail. I am running
Windows XP and use MS Outlook for pop3. For some strange reasons, I
got duplicate emails from some of the senders in Outlook, but not in
Web Mail. Why?

Hi,

Do you by any chance have 2 accounts configured in outlook that link
to the same pop3 mailbox (for instance 2 email aliases for a common
mailbox)?

Hi,

There is only one POP3 account in my MS Outlook. 99% of my emails are
Okay and appear only once in my Outlook. However, emails from a
certain users appear twice in my Outlook but only once in the same
webmail account. My colleagues (who are also on XP) is having similar
problems.

Hi,
do you have problem with disconnecting to the mail servers or internet
?
MS Outlook, or any other mail client delete or/and mark the mail that
he download only when he finish downloading all of them,
you got dubble mails becuase your client didnt finish download all the
new mails,
if you have problem with dubble mail only in the outlook you probably
have problem with you connection to the internet or to the mail
server,

to fix that you need to check what is the problem,
if the problem is:
1. modem disconnection problem: call your ISP and ask for "RasCheck"
to find a problem in your modem connection
2. server connection problem: it can be pasible that your mail server
is crashed and up crashed and up, i'll suggest to send a mail to the
mail operator and ask him about this type of problem.

Good Luck,
Bar

Make sure that you didn't set the 'Keep email on server' option.
This way, everytime you check your POP3, you will get multiple result.

The help document from Microsoft may help.  It is about a corrupted
index file that they give instructions for fixing.

There are other documents about duplicate messages, but, they
typically revolve around having more than one mail account configured,
which does not appear relevant to your case.

Hi.

Are you accessing pop3 mail account from two diferent desktops using
MS Outlook? If you are accessing same pop3 mail account from two
different desktops using MS Outlook, then MS Outlook show more than
one copies of email.

Hi, the link http://support.microsoft.com/default.aspx?scid=kb;en-us;Q314578
is for Outlook Express, but I am using MS Outlook.

Sometimes when we setup filters on incoming mail. If we have say two
rules to filter messages to a particular folder. We get two copies.

Example 
rule1 subject contains "hello" move to folder H
rule2 subject contains "hi" move to folder H

You get a mail with subject "hi hello"
You may end up with two copies in folder H

kc_at_work,
  I wish you were having better luck.  This was the most relevant
TechNote that I could find for Outlook... note that it is for Outlook
2002.  While I hope it helps, I find it hard to believe emptying the
trash is causing your trouble, as this note will suggest.  However, it
will give you an overview of what is happening in "Outlook's Mind"
when you download your mail.
  Good Luck.

It is possible that you are using fast user switching(Start and L).
This can not properly close down any ports open that Outlook has, and
can duplicate e-mail.
