BlackBerry Limited
BlackBerry Enterprise Server designates the middleware software package that is part of the BlackBerry wireless platform supplied by BlackBerry Limited. The software and service connects to messaging and collaboration software (MDaemon Messaging Server, Microsoft Exchange, Lotus Domino, Novell GroupWise) on enterprise networks and redirects emails and synchronizes contacts and calendaring information between servers, desktop workstations, and mobile devices. Some third-party connectors exist, including Scalix, Zarafa, Zimbra, and the Google Apps BES Connector, although these are not supported by BlackBerry Limited. As of June 2018, BlackBerry Enterprise Server has been renamed to BlackBerry Unified Endpoint Manager (UEM).
