Link: Exchange 2007 facing integration issues with other Microsoft software – Network World.
In a nutshell, Exchange 2007 can’t run on Microsoft’s most current virtualization software, Exchange’s management tools won’t run on the just released Vista desktop operating system and the 64-bit messaging server is not compatible with Microsoft’s forthcoming 64-bit server operating system called Longhorn. …
Ironically, users can run Exchange 2007 on the VMWare platform, which does support 64-bit guest systems, and some users are
making the switch.
VMware likes to compete by making better products. Case in point.
