Users will face new clustering limitations and will have to eliminate all Exchange 5.5 servers from their environments. In addition, they will not be able to do any in-place upgrades between Exchange 2000/2003 and Exchange 2007.
And Exchange no longer will have its own site topology but will run on top of Active Directory topology
Q. Why isn't Microsoft also delivering a 32-bit version of Exchange Server 2007?
A. Exchange Server 2007 is designed to be a stable, reliable enterprise messaging platform that delivers the fundamentals of e-mail and calendaring while providing innovative new capabilities. These new capabilities make the messaging system more cost effective and scalable for your organization and at the same time more productive for users accessing the system. Simply put, given the new capabilities of Exchange Server 2007, Microsoft could not guarantee a high-quality 32-bit version.
Q. Will I need Microsoft Windows Server 2003 x64 to run Exchange Server 2007?
A Yes, to deploy Exchange Server 2007, you will need an x64 edition of Windows Server 2003 or Windows Server 2003 R2. Volume-licensing customers are free to exchange their 32-bit version of Windows for the 64-bit version at any time, using their media kits.

Yes this is a blatant theft of the outline that Jess uses on her page, but I asked permission. Why?? Because I am a hardcore admin and can make ugly tables to make you developers frustrated, but this was too nice to pass up.
Yes, I write some of those dreaded admin cert exams you take. I won't say which ones so you don't come looking for me, but I will say they are the real good recent ones that have been coming out.
One dog, a Puggle. He eats anything that includes stuffing. Anything
Non-stop. At my desk, in my car, walking to work and back to my car downtown. In the house there is a crazy zoned set-up for you home automation geeks.
I am a self-proclaimed MP3 fiend, to which I have tried rehab 4 billion times to no avail. Next is the MP3 hard-drive for the car that I found. Now what kind of music you ask? I will never tell.
Get back to you here
Hershey’s Stomach of Holding: Jess and I are fighting over who eats more chocolate.
This will take far more time than I have today. I will start with I was born and still live in St. Louis, MO. Even though for a couple years I was never, ever here and always on the road, this is smack in the middle of the US. Everything is just a few hour flight. That part is nice. No beach/ocean/coast isn't the best. But with the travel I make up for it.

Looking to find me in person? Here is where I am and will be.
