BlackBerry Enterprise Server Express is a new service from Research in Motion, which allows you to set up a BlackBerry server for free and wirelessly synchronise your BlackBerry with Microsoft Exchange or Microsoft Windows Small Business Server.
This is great news for smaller businesses who previously might not have wanted to fork out for the full range of services available from BlackBerry Enterprise Server. Pricing details are laid out here in this pdf.
We’re told that BlackBerry Enterprise Server Express works with any of the networks’ data plans for BlackBerry phones. Obviously you’ll still have to pay for any out of bundle data charges which aren’t covered in your mobile contract, but there is no cost for the software itself.
