In the enterprise infrastructure, 2 hand held messaging platforms are dominant: Microsoft Exchange and BlackBerry Enterprise Server (BES). Windows Mobile phones and the iPhone use the ActiveSync MS Exchange Server information to sync up with your mailbox, whereas BlackBerry phones use a BES server.
In the current infrastructure I manage, our enterprise phones are BlackBerry devices. The BES links up with MS Exchange. When emails are received, they route to both servers. The main benefit here is if the MS Exchange network account is locked out, the BES continues to be able to send and receive messages.
In terms of being a user, I still preferred the iPhone over BlackBerry as I like the iPhone's OS. However, from an enterprise point of view, the decision makers seem to be more comfortable with a BES as it has a reputation of being more secure (whether this is true or not is a different story).
What are you experiences and thoughts on this?
