How to Set Connection Time-Out Limits for POP3

 

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

Topic Last Modified: 2007-08-22

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.

noteNote:
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.

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.

  1. In the console tree, expand Server Configuration, and then click Client Access.

  2. In the work pane, click the POP3 and IMAP4 tab.

  3. In the work pane, select POP3 and then, in the result pane, click Properties.

  4. On the POP3 Properties page, click the Connection tab.

  5. Under Time-out Settings, do one of the following:

    1. To set the connection time-out limit for idle authenticated connections, enter a number between 1 and 18000 in the box next to Authenticated time-out (seconds).
    2. To set the connection time out limit for idle unauthenticated connections, enter a number between 1 and 200 in the box next to Unauthenticated time-out (seconds).
  6. Click Apply, and then click OK to save your changes.

  • To set the connection time-out limit for idle authenticated connections, run the following command:

    Set -PopSettings -Identity CAS01 -AuthenticatedConnectionTimeout TimeValue
    
  • To set the connection time-out limit for idle unauthenticated connections, run the following command:

    Set -PopSettings -Identity CAS01 -PreAuthenticatedConnectionTimeout TimeValue
