This topic explains how to enable the Internet Message Access Protocol version 4rev1 (IMAP4) service for Microsoft Exchange Server 2007. When you install Exchange 2007, the IMAP4 service is not started. To enable the IMAP4 service, you can use the Services snap-in in Microsoft Management Console (MMC) or the Exchange Management Shell.

To perform this procedure, the account you use must be delegated the Exchange Server Administrator role and membership in the local Administrators group for the target server.
