Fair question. I think another one though is what would you suggest? Currently our Exchange Server Version doesnt support Ximian. That looks interesting but due to the server limitation I havent been able to try it. They are upgrading the Exchange Server to a version that will support Ximian soon (it was supposed to be done already). I will certainly give that a try. I am not aware of anything on any OS that gives the functionality of Outlook in an Exchange Server Environment. I am certainly willing to try other things as well and am open to suggestions.
