Enable POP3 in Exchange 2013

 

Applies to: Exchange Server 2013, Exchange Online

Topic Last Modified: 2013-03-13

When you install Microsoft Exchange Server 2013, POP3 client connectivity isn't enabled. To enable POP3 client connectivity, you need to start two POP3 services, the Microsoft Exchange POP3 service and the Microsoft Exchange POP3 Backend service. When you enable POP3, Exchange 2013 accepts unsecured POP3 client communications on port 110 and over port 995 using Secure Sockets Layer (SSL).

The Microsoft Exchange POP3 service runs on Exchange 2013 computers that are running the Client Access server role. The Microsoft Exchange POP3 Backend service runs on the Exchange 2013 computer that’s running the Mailbox server role. In environments with the Client Access and Mailbox roles on the same computer, you manage both services on the same computer.

For more information related to setting up POP3 and IMAP4, see POP3 and IMAP4.
