You can use the EMC and the Shell to configure Microsoft Exchange to use ports other than the default ports on the Microsoft Exchange Server 2010 server that has the POP3 and IMAP4 services enabled.

Note:
Enter IP addresses and IP address ranges in the Internet Protocol Version 4 (IPv4) format, Internet Protocol Version 6 (IPv6) format, or both formats. A default installation of Windows Server 2008 enables support for IPv4 and IPv6.
Note:
After you configure IP addresses and ports for POP3 and IMAP4 access, you must restart the POP3 or IMAP4 service. For information about how to restart the POP3 and IMAP4 services, see Start and Stop the POP3 Service and Start and Stop the IMAP4 Service.
