  • Artikel

Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

 

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

This topic explains how to use the Exchange Management Console and the Exchange Management Shell to configure the connection time-out limits for idle authenticated and unauthenticated Post Office Protocol version 3 (POP3) connections. In the original release (RTM) version of Exchange 2007, you could only set connection time-out limits for POP3 by using the Exchange Management Shell. In Exchange 2007 Service Pack 1 (SP1), you can also set connection time-out limits for POP3 by using the Exchange Management Console. Steps for doing this are included in this topic.

Note

After you have set the connection time-out limits for POP3, 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 procedures on a computer that has the POP3 service enabled, 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 2007, see Permission Considerations.
