This topic describes how to enable or disable Post Office Protocol version 3 (POP3) access for a user on the computer that is running Microsoft Exchange Server 2007 that has the Client Access server role installed and the POP3 service enabled. In the original release (RTM) version of Exchange 2007, you could only enable or disable POP3 access for a user by using the Exchange Management Shell. In Exchange 2007 Service Pack 1 (SP1), you can also enable or disable POP3 access for a user by using the Exchange Management Console. Steps for doing this are included in this topic.

Note

After you have enabled or disabled POP3 access for a user, you must restart the POP3 service. For more information about how to restart the POP3 service, see How to Start and Stop the POP3 Service.

Before You Begin

To perform the following procedure on a computer that has the POP3 service enabled, the account you use must be delegated the Exchange Server Administrator role and membership in the local Administrator group for the target server.

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