This may be not overly relevant to many environments, but Microsoft is finally releasing a solution for backing up Exchange 2007 when running on Windows Server 2008. When you install Exchange 2007 SP2 the functionality is added.
If you have SBS2008, this functionality is already there. If you are a large organization, you likely have third party backup software that performs Exchange 2007 backups. However, for mid-sized organizations trying to save a few $ on backup software, this is a life saver. I know of one client that will start using this immediately.
