The RIM BlackBerry Enterprise Server (BES) serves as a centralized link between a company’s enterprise infrastructure and messaging platform with the company’s mobile wireless users.
To use BES to deploy applications to BlackBerry devices, make sure of the following before you install the offline client on the BlackBerry device:
The RIM BES software is installed and configured correctly, using the RIM installation documentation.
The RIM BlackBerry Desktop Manager software is installed and configured correctly. The minimum requirement for the BlackBerry Desktop Manager software is version 4.0.
The BlackBerry device has connectivity with BES, and that you can synchronize between BES and the BlackBerry device.
