What is BlackBerry Enterprise Server Express (BESX)?

BlackBerry Enterprise Server Express, BES Express or BESX, is a middleware application that allows the connection of BlackBerry devices, to enterprise grade email, messaging and collaboration platforms such as Microsoft Exchange Server.

Email hosting companies that offer hosted exchange accounts, use BlackBerry Enterprise Server Express to enable BlackBerry owners to make use of the services they offer. BES Express enables the synchronization of email, calendar and contacts with a hosted exchange server, just as Microsoft Exchange ActiveSync does natively.

The best email hosting companies that provide hosted exchange services include BlackBerry Enterprise Server Express access as standard, allowing Blackberry users to connect to the hosted exchange server in real-time. In effect, BESX enables BlackBerry devices to be turned into fully featured Microsoft Exchange clients, despite the fact that Microsoft Exchange ActiveSync is not built in to BlackBerry OS.
