This book is an ideal compliment to someone who knows a little about Outlook already, this increases your skill set with what you can accomplish with Outlook.
The is a book that is more designed to be used as a reference book rather than read from cover to cover.
This book would be better renamed to A Detailed Introduction Into Everything Outlook, as it introduces you to everything, from message protocols, Exchange Server, VB Script, Designing Forms and using VBA; but it would is not a reference book for an Exchange Server Admin, or a developer developing Outlook solutions.
I have given the book 4 stars, one star removed because I feel the chapters are all muddled up, it introduces you to the message protocols in chapter 1, yet it is quite a bit later before you are shown how to even send an email! Hence I thought one star last for this erractic arranging of subjects.
