How to Configure POP3 Access to Exchange 2003 Servers

 

Applies to: Exchange Server 2007 SP3, Exchange Server 2007 SP2, Exchange Server 2007 SP1, Exchange Server 2007

Topic Last Modified: 2007-02-19

This topic explains how to use the Exchange Management Shell to configure your connectivity options for connecting to Microsoft Exchange Server 2003 servers by using Post Office Protocol version 3 (POP3). By using the settings for this cmdlet, you can specify the ports to use to connect Microsoft Exchange Server 2007 computers that have the Client Access server role installed to Exchange 2003 servers. By default, this value should be set to use port 110. This cmdlet also lets you disable access to Exchange 2003 servers.

noteNote:
After you have configured POP3 access to Exchange 2003, 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.

You can configure Exchange 2007 Client Access servers to connect to mailboxes located on Exchange 2003 servers. However, when you do this, you must disable Secure Sockets Layer (SSL) encryption and enable Basic authentication on the Exchange 2003 server. Because the user name and password are sent in clear text when Basic authentication is used without encryption, we recommended that you secure the traffic between the Client Access server and Exchange Server 2003 server by using Internet Protocol security (IPsec).

To perform the following procedures 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 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.

  1. To configure POP3 access to Exchange 2003 servers by using the default port value of 110, run the following command:

    Set-PopSettings -ProxyTargetPort 110
    
  2. To disable POP3 access to Exchange 2003 servers, run the following command:

    Set-PopSettings -ProxyTargetPort 0
    

For more information about syntax and parameters, see Set-POPSettings.
