I read this article which explains that Exchange Server 2003 is actually supposed to work: http://crave.cnet.co.uk/software/0,39029471,49303381,00.htm Exchange Support Apple has built in support for Microsoft's Exchange Server 2007. This is what, on a PC, pushes and synchronises all your email, contact info and calendar entries to Outlook and your phone. By doing this, OS X's Mail, iCal and Address Book apps sync up just like Outlook. Note that if your company is still running Exchange Server 2003 (ours is), you will still be able to sync Snow Leopard with your office server. We confirmed this with Microsoft, a spokesperson from which said, "Correct -- it will work with Exchange Server 2003 as well." Our IT boffins here at CBSi confirmed this too. I know it's still early, but has anyone had any luck getting this to work? I'm about 30 minutes away from installing the $29 SL on my laptop. And I'm really hoping to have the ability to eliminate having a PC desktop on at work strictly for the connection to our exchange server 2003.
