Hi How can I confirm if this is already installed on my Exchange 2010 server? Where do I look to confirm this Thanks

You don't install it on the Exchange server normally. It is installed on to another server for something like BES to be installed. It will appear in Add/Remove programs. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.

i have to install BES. Should BES be placed on teh same server as Exchange 2010. What is the best practice. Thanks

Not it's not supported. Unsupported Environments The BlackBerry Enterprise Server and BlackBerry Enterprise Server components do not support installation on the same computer as the messaging server. http://docs.blackberry.com/en/admin/deliverables/12044/BlackBerry_Enterprise_Server_for_Microsoft_Exchange-Installation_and_Configuration_Guide--819071-1029033521-001-5.0.1-US.pdfJames Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com
