The Outlook team in Redmond is aware they have an issue but they are unable to track it down as of yet (received a response email tonight). Although bill isn't having any issue with Vista 64-bit there are others reporting issues with Vista. That's the real issue for the Outlook team right now, they cannot pin-point the problem.
