Answer Wiki:
Do you need POP3? If all your clients are using Outlook and part of your domain then Exchange doesn't need POP3. The only use I've found for it is with the Macintosh clients within our domain because their mail client requires it. Sounds to me like you're having a problem between your Exchange server and your clients. Please provide additional details about the email client your users are using.

Lord good to see you back
i want to know in exchange server 2003 which default protocol is used to receive mails in outlook 2003
The default is IMAP4.
You can set up a new account with POP3 also. I have had users do that on a different pc then the one they usually use and then wonder why all their mail “disappears” from the other machine afterwards. Fun!
But some told me that IMAP4 is disabled in exchange server 2003 and SMTP is used for receiving and sending emails. how we will know that mails are receving by SMTP or IMAP4.
First off, the basics: IMAP and POP are for retrieving mail. SMTP is for sending mail to a server for delivery.
I can only guess at an answer, perhaps Microsoft found that far more people use other clients to access mail than MS Outlook and so made the default enabled in Exchange 2007.
Indeed, the POP thing was the bane of my existence at an old employer. We have the same thing now with BB access for some people. “How come if I delete it on my BlackBerry, it’s gone on my desktop email too??”
We are having a stranger problem, they are supposedly enabled on Exchange 2003, but sometimes the ports work, sometimes they are closed before even the opening message as if there is a firewall/Anti-Virus software running, yet our IT guy can’t seem to figure it out and get it working and swears there isn’t any such software.
I vaguely recall in Exchange 5.5 (the last time I worked directly with Exchange), there were allowed subnet settings, but our subnets are pretty much fixed. It’s vexing, as the entire engineering department works on Macs and Exchange 2003 is too old for Mac Office Outlook, but IMAP isn’t working and OWA is well, less than stellar for all the email we handle.
The TechNet articles I found are lacking in any substance whatsoever on the subject of IMAP properties configuration in Exchange 2003.
