In the past 12 years, we have written a book on every version of Exchange since its inception built on at least two years of early adopter beta experience. This book, Microsoft Exchange Server 2007 Unleashed, is the latest of our efforts. However, unlike the past two major releases of Exchange (2000 and 2003), Microsoft Exchange Server 2007, although very similar, had enough differences that it required complete rethinking of the way we wrote this book. | Rand Morimoto Michael Noel Andrew Abbate Chris Amaris Mark Weinhardt Microsoft Exchange Server 2007 UNLEASHED Rand H.
