A server component from BlackBerry that synchronizes mail and calendar data between BlackBerry phones and enterprise messaging servers, primarily Microsoft Exchange. By supporting corporate email, BlackBerry Enterprise Server (BES) was the major ingredient that enabled BlackBerry phones to take off in the 2000s.
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
