The Exchange 2007 SP2 download is available right now. Besides being a service pack, Exchange 2007 SP2 is also a “feature pack”, meaning it introduces new functionality including the ability to backup Exchange natively using Windows 2008 backup amonst other features.

Checkout the Exchange teams blog post on the new features.

 Henrik Walther wrote a great article exposing the new backup functionality, which should buy some much needed relief for folks who have wanted to deploy Exchange 2007 but have not had a backup solution for it.
