If you want to impress your friends and colleagues or just have a reference poster for Exchange 2007 - there is a great poster available here
It covers everything in Exchange 2007 and is great to print out and put on the wall.
So the next time someone says it is only email - just point them in the direction of the poster, hopefully they will get an understanding of what you look after or implement every day.
How can I get a full size "glossy" of this for my classrooms, like the Windows Server 2008 posters from the TechNet magazine?
A fine document indeed. I'll be sure to be impressing my friends down the pub with this tonight :)
