As some of you may have heard, there are some changes to the next version of Exchange, specifically around 64 bit and that 64 bit will be the only released version.    So you may have some of these questions:

Why did Microsoft make the decision to offer Exchange 12 as a 64-bit only application?

Isn’t 64 bit only required for very high scale customers?

Will customers who want to upgrade to Exchange 12 be required to purchase new hardware?

These are some great questions and one of my colleagues Harold Wong has the answers!!!!! Check out his recent posting on Exchange 12.
