Outlook Troubleshooting

Duplicate Emails

There are a few of situations which may cause Outlook to download duplicate messages:

1. Outlook Downloads Messages from a POP3 Server Twice http://support.microsoft.com/default.aspx?scid=kb;en-us;292249
2. Mail Retrieval Problems Occur When You Receive POP Mail http://support.microsoft.com/default.aspx?scid=kb;en-us;317945
3. Password Prompt, Duplicate Messages Appear If Outlook Profile Has Two POP3 Accounts http://support.microsoft.com/default.aspx?scid=kb;en-us;284404&Product=ol2002
4. POP3 Headers Are Duplicated http://support.microsoft.com/default.aspx?scid=kb;en-us;289942&Product=ol2002
5. You are Using Anti-Virus Software Many anti-virus programs can cause this issue as well. If the message is large, the software causes a 'timeout'. As a result you recieve the message over and over.

How can I stop this situation?

The easiest and fastest solution to this problem is to log-in to the mail server and delete your mail message that is causing the problem - or all of them for a fresh start. (NOTE: make sure that you have downloaded your messages first)
