Type "Microsoft Help and Support" in your favourite search engine and then click on the link which leads to the page. In the upper right hand corner type in "70-236" (note: do not type in the ISBN number as it will not return any results - contrary to what Microsoft says) and you will then see a link for the errata page for the book in question. You can use this for any of the Microsoft Press Training Kits (each of which has a pretty staggering amount of typos). This 70-236 Training Kit has so many typos that the errata listing had to be broken down into two separate links each of which contains dozens and dozens and dozens of corrected errors. Trying to use any of these Training Kits without access to the errata pages is aggravating beyond belief - especially when attempting to to the labs - but the written information tends to both informative and well-written. Hope this helps...

4 stars if it did not have errors.
I bought this book and am currently rereading it. I passed the 70-236 with more than the help of this book. I think the book is a good book to learn Exchange 2007. Unfortunately, it has A LOT of errors. Make sure you go to: http://support.microsoft.com/kb/947010/en-us to make the listed corrections to your book. Some are not listed yet (i.e. the Quick Check Answer at the bottom of p233 has a period that should not be there).

I was amazed at how poorly a book can be written. Where was the editor on this book? DO NOT purchase this book to pass exams. You will get things wrong on the exams because of this book and the poor explanations.

Next at a time when CD's at the end of the book contain video and audio, perfectly matched questions to the book and explanations to the answers that allow you to click back to the section to read why the answer they chose is correct, this book DOES NOT do that at all. The questions on the CD had to come from a completely unrelated source.

Please look at the other books for Exchange like Sybex 047018146X. Two exams are covered and it is reall comprehensive. (No I am not associated with the publisher), but I did use the book to easily pass the exam.
It has a CD that contains:
SYBEX TEST ENGINE:
Test your knowledge with advanced testing software. Includes all chapter review questions and bonus exams.

ELECTRONIC FLASHCARDS:
Reinforce your understanding with flashcards that can run on your PC, Pocket PC, or Palm handheld.

Also on CD, you'll find the entire book in searchable and printable PDF. Study anywhere, any time, and approach the exam with confidence.

OR Microsoft Exchange Server 2007: Tony Redmond's Guide to Successful Implementation (Paperback)which has more practical information which can be used in the field.

This book is HORRIBLE. This is my 3rd Microsoft book that I have purchased and I will not be buying any more. My logic was "a Microsoft book should help me pass a Microsoft test right?" WRONG.

First of all, the book is FILLED with blatant mistakes and misspelled words. A pattern I've noticed with the Microsoft books is that they fill you with 95% of stuff that's not covered on the exam. So when you take the test, I can guarantee you will see things on the test that weren't in the book.

If you just need to learn about Exchange, then this book is fine for that (although the misspelled words and errors will still throw you off). But if you need a book to pass the exam, stay away from Microsoft. 95% of the Powershell commands that you need to know for the test are NOT in this book.

I truly believe this book series needs to stop advertising that it will adequately prepare you for the exam because it doesn't. And the fact that they couldn't even bother to check their facts and spelling makes me want my money back.

After 2(fulltime)days, i am at page 124!?!?!?!? Due to the poor editing examples walkthroughs etc. You spend your time more Googling for resolving errors and why stuff don't work like the writers intended to work. Now i am not a newbe in this field and working in the ICT for the last 10 years. I have installed on a 2003 box sql 2005 IIS6 and and exchange 2007. And used 2007 to get mail functionality within PHPBB. It took me almost a week(SQL rights with IIS6) and setting up the database. But after 2 days spending time to wrestle to page 124, you really are in pain. I also bought the other REDMOND book another reviewer opted. And will look if it gives the salvation i need.

Dear Orin and Ian, i know it's though to write a studyguide. With a hugh time constrain. Were also family man right!!!!! But the editing of this guide is really poor. There are smarter ways of telling things, wich cuts in editing time and headaches of your readers. Still the 70-291 is the best Microsoft study guide. I've red.

First the negatives
+ Loads of mainly minor editing mistakes everywhere, the main body of the text and Q+A at the end of every chapter,
+ The additional tests on the CD are pretty good, but annoyingly the Q+A are not alligned with the book. In most cases you have to go through 2 chapters before being able to test yourself.
+ In the last chapter LCR is not taken through its logical conclusion.
+ The online site does not provide an errata/corrections list.

Postives
+ Covers the material well enough
+ Each chapter has at its end a Q+A section, to re-enforce learning.
+ You get Exchange 2007 32bit+64bit on to DVD plus additional questions on a CD.
+ loads of screenshots, text pretty easy to read

I used this as my main study tool and passed with 96%, so it does what it says.

I would give it 5 stars, if it didnt has so many annoying errors. I think it is unfair and too harsh to lose more than a single star, as

1. This is a technical book and it has a limited life span (3 years max).
2. The authors and publisher are in a race to produce the book for people like me, I rather have the book now with a few errors rather than wait for another 3 months.
3. Most of the errors probably will be corrected with time.

This book is actually about a 2.5. I have been working on exchange 2007 now since just days after its release and have been involved in several medium sized company deployments and one 6500 user migration from groupwise. While this book for the most part is ok information it has so many editing errors, and a few major technical erros I stopped writing them down after Chapter 5. Many of the practices/examples in the book especially relating to powershell scripting flat out won't work. For instance they have you write a ps script that will move-mailbox and tell you that you can schedule it. What they don't include with that is move-mailbox contains a confirmation dialog and they do not explain anywhere in the entire book how to get around it. In other words if you do what they say the next morning you will come into a Yes, No, etc prompt. In many of their scripting examples they forget to close a quote or tick which of course makes the examples not work. If you haven't worked with PS or Exchange 2007 you will probably find this book frustrating if not downright maddening due to the poor editing. It would be a good book for a beginner if the editors had simply done their job. The primary reason purchased this book was for exam prep-which it is very good for minus the editing. When I was finished I felt better prepared for the exam but did not really feel as if any professional knowledge was garnered from the read. Lastly the technical ability of the authors is ok, not anywhere near expert, multiple times in the book they suggest NLB for Hub Transport servers which is not supported or recommended...its a terrible idea that causes lots of problems. There were points where I felt they had never actually seen the product or read the documentation, and other parts where I thought they had some generic lab experience with no real world experience. Overall though compared to Tony redmond's Guide to Successful Implementation this is the better of the two books if looking for a cert prep ONLY. If looking for useful knowledge go Unleached or Tony's book or both :)

in think amazon made a mistake.
the reviews that should appear here should be for exchange 2007 cert 70-236 and not for the 70-620 which is for vista. None the-less good job amazon.
