Microsoft release Exchange 2010 Beta to public

I was amazed to see today that the public beta of Exchange 2010 is already available. I must be getting old but it just doesn't seem long enough since the release of Exchange 2007 to be having to start boning up on a new release.

Anyway there is plenty of information to start with at the following links: -
