An easy to read introduction to Exchange 2010
on 9 September 2012
This would be a good book to read before installing Exchange 2010. It is not heavy going like most other manuals. However, it does miss out many essential elements, for example:
It has a short section on the new archive function, but it does not explain how to access the archive mailboxes once created. It does not cover the complex licensing system, which in my opinion is absolutely key in any practical approach to Microsoft software. For example, in order to access the archives one requires an Office 2010 Pro Plus licence for each user, and as far as I am aware you cannot upgrade from an Office or Office Pro licence. It does not cover precisely which functions require an Enterprise CAL and which do not. Critically for planning purposes does the Default Archive Tag require an ECAL or not?
It does not warn the installer that the new 2010 log file system can easily generate log files more than 3 times the total size of the mailboxes, and so if you do not set up Windows Server Backup ( "WSB" ) before you start migrating mailboxes you will soon run out of disc space. WSB is mentioned, but not until page 173 - by which time it could be too late.
It does not cover the ideal partition sizes and content for a single server setup, so you will probably have to migrate things around after the initial installation unless you do your own research on this first.
Having said all that, I am not able to recommend a better book on Exchange 2010 - only the Microsoft Technet site, which can be heavy going. At the price this book is probably worth buying if you are still in the planning stage. It will save you time, even if it does not have all the answers you will need.
