Next you learn about Exchange Administrator, the front end that enables users to access and edit Exchange Server's operation. The book usefully lists the containers--the components underlying Exchange Server--which Administrator controls. At this point, you start to get your hands dirty. The sheer wealth of practical detail that follows--particularly the sections on managing Internet mail and security--calls for careful examination.
Robichaux clearly knows his subject. He doesn't slavishly tow the Microsoft line and is happy to make suggestions based on real experience. For example, he recommends against using Exchange Server's automatic restart feature. If you're responsible for installing and managing Exchange Server, you should have this book on your shelf. --Steve Patient, amazon.co.uk
