Exchange2007- Before SP1

Before Exchange SP1 it was not possible to enable the POP3 and IMAP services using Exchange Management Console (EMC). The only was to use PowerShell Cmdlet. Now SP1 has made it possible.

PS>Start-service MSExchange IMAP4

PS>Set-service MSExchange IMAP4 Startup type Automatic

You gotta learn PowerShell.
