I recently read two books, “MCITP Self-Paced Training Kit (Exam 70-237): Designing Messaging Solutions with Microsoft Exchange Server 2007” (http://www.microsoft.com/learning/en/us/Books/10937.aspx) and “MCITP Self-Paced Training Kit (Exam 70-238): Deploying Messaging Solutions with Microsoft® Exchange Server 2007” (http://www.microsoft.com/learning/en/us/Books/10938.aspx) that have a lot of information about Exchange 2007.
They are written as a study guide towards the exams, so they begin with instructions how to build your own lab environment followed by lessons and now and then also practices. I like this format since it gives the reader some theoretical knowledge and then they practice on it, this also needed if you want to really learn and pass the exams. I recommend that you take your time and use your lab do the practice tests thorogfully.
Both books have a lot of words and content, and if you really read and give it some thought you will learn a lot, but if you only read it fast from cover to cover you will probably not pick up that much new knowledge.
The overall impression is that those books are well written with an easy language to understand, they also have a lot of content to read through but on the other hand, Exchange is a big product with a lot of features.
Keep on reading.
