I'm looking to deploy a large BES implementation with Zimbra. Having trouble finding a planning guide guide for the the design effort. Traditionally, under other messaging Platforms (Exchange, Notes, Etc.), BlackBerry Enterprise Server will accommodate 2,000 Users per Server. I am planning on deploying Zimbra and 22,000 BES Users. Will the Zimbra BES Connector support this same capacity as with Exchange (2,000 Users)? Does anyone have any design experience or reference material they can recommend.
