Note Although this article discusses an error message that may occur on a local computer, the problem actually occurs in Microsoft Exchange 2000 Server. To resolve this issue and prevent error messages on the local computer, an update must be applied to the Exchange server that the Microsoft Outlook application is configured to use or to communicate with.
When you try to use Microsoft Outlook Express to retrieve a message from a Post Office Protocol (POP3) e-mail server, you may receive the following error message:

If you try to retrieve the same e-mail message by using Internet Messaging Access Protocol (IMAP), you may receive the following error message:
