  • Article

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

By default, Post Office Protocol version 3 (POP3) is disabled in Microsoft Exchange Server 2007. After you enable POP3, Exchange 2007 accepts unsecured POP3 client communications on port 110 and over Port 995 using Secure Sockets Layer (SSL).

You can perform the following procedures by using the Exchange 2007 computer that has the Client Access server role installed.

Before You Begin

To perform the following procedures on a computer that has the Client Access server role installed, you must log on by using a domain account that has the permissions assigned to the Local Service Account. The account must also be a member of the local Administrators group on that computer.

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

To use Microsoft Management Console to start and stop the POP3 service

  1. Click Start, point to Programs, point to Administrative Tools, and then click Services.

  2. To start the Microsoft Exchange POP3 service, in the results pane, right-click Microsoft Exchange POP3, and then click Start.

  3. To stop the Microsoft Exchange POP3 service, in the results pane, right-click Microsoft Exchange POP3, and then click Stop.

To use net start to start and stop the POP3 service
