BlackBerry-maker Research In Motion (RIM) this week released a new software maintenance update for BlackBerry Enterprise Server (BES) 5.0 service pack 2 (5.0.2) for both Microsoft Exchange and IBM Lotus Domino deployments.\n\nBlackBerry Enterprise Server (BES) Diagram\n\nBES 5.0.2 maintenance release 3 (MR3) fixes a number of known issues with earlier version of BES 5.0.2 for Exchange and Domino. Specifically, BES 5.0.2 MR3 resolves bugs related to the BES BlackBerry Administration Service, the BlackBerry Messaging Agent and the BlackBerry Monitoring Service, among other fixes to core BES components. And the update patches another security flaw in BES 5.0.2, identified by RIM earlier this month, and related yet again to the BES BlackBerry Attachment Service's troublesome PDF Distiller tool. \n\n\n\nThe 5.0.2 MR3 update is currently only available for Exchange and Domino, and it doesn't seem to affect BES Express deployments. BES Express is a slimmed down, free version of BES for organizations that may not demand the level of BlackBerry security and IT control available via full BES.\n\n\n\n\nThe last major BES 5.0.2 maintenance update was issued last November. RIM is also expected to release the next version of BES, 5.0.3, "very, very soon." BES 5.0.3 will be the first BlackBerry server to features RIM's new BlackBerry Balance service, which is designed to help BlackBerry admins separate potentially-sensitive corporate data and personal information on users' smartphones.
