- You create an Outlook profile for a Post Office Protocol 3 (POP3) user in a Microsoft Exchange Server 2010 environment.
- You configure Outlook to download POP3 email messages to an Exchange Server 2010 mailbox. For example, you enable the Leave a copy of messages on the server setting when you configure the POP3 account.
In this scenario, Outlook downloads all POP3 email messages every time it starts. Therefore, duplicated POP3 email messages are in the mailbox.
Note You expect Outlook to download these messages only once.
