We have a BES 5.2 server and an exchange 2003 server.
Recently installed a Exchange 2010 server but need to be able to run in co-existence for a while, and let BES users still have access to Blackberry's but be on both servers.
I was thinking about doing this:
Create new BES account i.e.. bes2010 on the exchange 2010 server..assign it the correct permissions etc etc, then install the correct MAPI CDO on the BES server, and change the AD account that the BES server uses to the bes2010 account that I setup on the exchange 2010 server.
Will that allow users to be on both servers and still have access to the BES server?
