Enabling Virtual Servers for POP3 and IMAP4

When Exchange Server 2003 is installed, the IMAP4 and POP3 virtual servers are disabled. These services should be enabled and configured to automatically start using the services node in the Computer Management console. Without performing this task, users cannot retrieve mail from the server using POP3 or IMAP4 protocols. These services are called:

• Microsoft Exchange IMAP4

• Microsoft Exchange POP3

After these services are enabled, the Exchange System Manager (shown in Figure 2.20) can be used to control the services.
