Can I receive email from an MS Exchange server using POP or IMAP on my iPhone?

"Yes, your iPhone can receive mail from an Exchange server via POP or IMAP provided they are turned on.

If you have already set up POP with the Blackberries you simply need to use the same settings you would have entered for your Service Books on your iPhone.

If you don't have IMAP enabled you can turn it on (instructions vary depending on your version) and then use the same settings.

For more info on enabling IMAP on Exchange check your documentation or TechNet: Exchange 2003 or Exchange 2007"

"You could move your GMail account away from ActiveSync, thus freeing up the single Exchange account for your work account. You'll then have to handle your email, calendar and contacts separately:

Use IMAP to sync your mail.

Use CalDAV to sync your calendar.

Use iTunes to sync your contacts.

This is how I had my iPhone set up before moving to ActiveSync, and it works reasonably well."
