I receive duplicate e-mails when using Outlook

Duplicate Email Messages In Outlook/Outlook Express

If you are receiving duplicate e-mail messages on your computer when using Outlook or Outlook Express, there may be a corrupted e-mail within your in-box on the mail server. To delete the corrupted message follow these steps:

1. Login to your Webmail Account:
   
   Open your web browser and access your webmail account using this link: https://www.MyDomain.com/webmail
   (*Change "MyDomain" to your actual domain name)
   
   
2. Enter your User Name (e.g. your Full E-mail Address) and Password
   
   
3. Delete the corrupted/damaged message(s) that is creating the duplicates on your computer
   
   (You may want to delete all of your in-box messages on the server, AFTER you have downloaded them within Outlook or Outlook Express.)

Possible Causes of Duplicate Emails on Outlook Express

Problem:
The "Leave Messages on the Server" box has been checked in your Outlook/Outlook Express account settings.

Fix:
Uncheck the "Leave Messages on the Server" box.

1. Click the menu option at the top of Outlook/Outlook Express: Tools » Accounts
   
   
2. In the window that opens (Internet Accounts), select the Mail Tab
   
   
3. Click on the Mail Account, then select Properties » Advanced
   
   
4. Remove the checkmark in the box "Leave a copy of messages on server"

Additional Information

The following information is taken from Microsoft Help and Support.

Problem:
Outlook/Outlook Express downloads e-mail messages from a POP3 server twice. Outlook downloads messages from a Post Office Protocol 3 (POP3) server again after it empties the Deleted Items folder, even if you have both the "Leave a copy of messages on the server" and the "Remove from server when deleted from Deleted Items" options enabled on the POP3 account.

Fix:
There is not an available workaround for this problem. Simply delete the duplicate messages.
