How to configure IMAP for sending email in Exchange 2010

Last Modified: 2012-06-21

I enable the IMAP protocol in Exchange 2010 and configure my Outlook profile to connect to a mailbox by using IMAP.  I can send email to my mailbox from Gmail but when I try to send back or reply an email via IMAP, it does not send.  It shows in Sent items folder but when I check my Gmail account, the email did not get there.

What should I turn on?

You send using SMTP and you download using IMAP.

When you enter the outgoing email server you need to specify that it uses port 587 (this port must be forwarded to your exchange servers IP address from your router/firewall if you are external to the network).

You will also need to specify a username and password in the form of DOMAIN\Username and your usual domain password.


I just need to send from inside of my internal LAN.  Any configuration doc can be used?
