|Go to your web mail server and delete all messages in the Inbox. Then, if this doesn't solve the problem, on Outlook go to menu File –> Info –> Account Settings –> E-mail tab. Double click on the e-mail account with the problem, click on the More Settings... button, and chose the Advanced tab; on the last three lines (controlling the messages to leave or delete on the server) make sure all three boxes are unchecked.|
Hope this helps. If it does post it here, please.
