  • 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) and Internet Message Access Protocol Version 4 rev1 (IMAP4) are disabled in Microsoft Exchange Server 2007. To use these protocols, you must first start the POP3 and IMAP4 services on the computer that is running Exchange 2007. You must also configure SMTP for your POP3 and IMAP4 clients to send e-mail.

For detailed steps for how to enable the POP3 and IMAP4 services, see How to Enable POP3 in Exchange 2007 and How to Enable IMAP4 in Exchange 2007.
