Adding IMAP4 and POP3 Resources


Topic Last Modified: 2005-05-13

For improved security, the Windows IMAP4 and POP3 protocol services are no longer enabled by default on servers that are running Windows Server 2003. Similarly, the IMAP4 and POP3 protocol resources are no longer created by default upon creation of an Exchange 2003 virtual server.

If you want to enable either of those protocols, you must do the following:

  • Enable the Windows IMAP4 or POP3 service on those cluster nodes that will be running the Exchange Virtual Server with the IMAP4 or POP3 resource. To make sure that the service works correctly with clustering, you must also configure the service to start manually. For detailed instructions, see "How to Enable a POP3, IMAP4, or NNTP Virtual Server" in the Exchange Server 2003 Client Access Guide.

  • Manually add the respective IMAP4 or POP3 virtual server as a resource to each Exchange Virtual Server on which you want to enable the selected protocol, and then bring the resource online. For detailed instructions, see How to Add an IMAP4 or POP3 Virtual Server as a Resource to an Exchange Virtual Server.
