Lots of people know about BlackBerry. BlackBerry / BES allows you to connect a client (BlackBerry handheld) to your Exchange environment. You create a management account, grant it the requisite permissions and you're off. What are you looking to find out about? You might want to give this book a look . http://tinyurl.com/35j8yh or check out the documentation at http://www.blackberry.com/support. http://www.blackberryforums.com is also an excellent resource.
