Microsoft Announces Exchange 12 Beta 1

"Beta 1 of Exchange 12 is a private one that will be released to a mix of 1,400 customers and partners worldwide"

Thankfully, Beta 1 will be available to testers in both 32bit and 64bit.  Obviously, the benefits of 64bit will not be realized by the testers who deploy the 32bit version, but there is still plenty of opportunity to run the product through its paces and report on the new features.

Beta 2 is anticipated in mid-2006 and the final release in early 2007, according to Sr Product Manager Megan Kidd, as referenced in this ARNNet article.
