BlackBerry Enterprise Server - Computer Definition
The server component from BlackBerry that synchronizes mail and calendar data between BlackBerry phones and the enterprise's messaging servers: Microsoft Exchange, IBM Lotus Domino and Novell Groupwise. BlackBerry Enterprise Server (BES) was the major ingredient that enabled BlackBerry phones to take off in the 2000s. Third-party software for other mail servers is also available. In January 2013, BES 10 was introduced, a major upgrade that provides a single console for managing BlackBerry 10, Apple iOS and Android devices. See BlackBerry, BlackBerry 10 and BlackBerry Balance.
