This topic explains how to use the Exchange Management Shell to configure Microsoft Exchange to use ports other than the default ports for IMAP4 authentication.

Note:
After you have configured ports for IMAP4, you must restart the IMAP4 service. For more information about how to restart the IMAP4 service, see How to Start and Stop the IMAP4 Service.

Before You Begin

To perform this procedure, the account you use must be delegated the Exchange Server Administrators role and membership in the local Administrators group for the target server.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.
