As a Mac user, my first reaction is NO! But then, perhaps you've sorted this out for us too. IE is no longer supported.

Actually, MS Entourage 2004 for is native to Exchange and runs well on Macs, and Microsoft announced plans to realease a new updated version in Office 2008 later this year (2007). I almost forgot to mention, Apple's own Mail client is Exchange compliant!

The Apple mail does work with Exchange IMAP services, though it is not a native Exchange client. For a native Exchange client, you will need to get Microsoft Entourage 2004, or 2008.
