Our company uses a Hosted Exchange which apparently does not have BES support there.

I tried to install the BES Express 5 but can't seem to go pass the MAPI Settings section. Following is the error: "The setup application could not contact the Microsoft Exchange Server to check the name of the mailbox"

Can anyone help? Or is it actually impossible to have Exchange and BES installed on different network?

The error's pretty self explanatory - your BES server can't contact your Exchange server. Might be a misconfiguration on the BES server, a firewall rule blocking the communication, a missing route in your network... really, the possible causes are nearly endless, and you haven't given nearly enough information for anyone to do more than take shots in the dark.

Having said that, one of my previous jobs used BES and hosted Exchange, both of which I set up, so it's certainly possible to run a setup like the one you're describing, with BES on a different network from Exchange.

Good to hear that it is possible. I actually followed the instructions here, but skipped all steps that requires Exchange because I have no control of that:… – friend Feb 25 '13 at 6:22
My problem is I am completely new on this thing and all examples I found on net has always been installing BESX with Exchange on same network. – friend Feb 25 '13 at 6:24
@bong Well, just because you have hosted Exchange doesn't mean you can skip all the Exchange steps. You still need those steps performed to get BES and Exchange communicating. If you have access to the Exchange server hosting your email, do those steps yourself, if not, you'll have to get your host to perform them for you. – HopelessN00b Feb 25 '13 at 17:11
One of the step requires is to "add permission to BESAdmin via Exchange management shell console". If they don't give me access to this, is that means what am trying to do is impossible? How did you do it in the past? Thanks – friend Feb 26 '13 at 0:24
@bong Well, if they don't give you access to EMC, you tell them to perform [the following steps] and tell you when they're done. As to how I did it in the past, I worked with hosts who gave me access to the Exchange environment they hosted for us. You can't connect remotely to your Exchange instance with EMC or EMS? – HopelessN00b Feb 26 '13 at 2:40
