Ebook: Microsoft Exchange Server 2007 Administrator's Companion (Pro - Administrator's Companion)

This book is very thin on where you need it most. For instance, only the very very basics of SCR is mentioned. They do not even mention how to restore SCR. Try another book. Add-ADPermission, a command that is commonly used in Exchange, is not even found. A thick book, but nothing really covered well. Maybe a good book if you are brand new to exchange, and want something to read from cover to cover. You will be left in the dark if you use this a companion.
