Have a Verizon 8830 bb on BES. Our company runs Microsoft Office Live Communicator for our im client and I'm wondering if I can get it on my bb. Where do I go to install the app on my bb? Thanks!

Your IT Department (including the BES Admin) needs to set that up for you. There are configuation settings on the BES as well as a webserver that has to be setup/configured for Live Communicator.

THEN they can push the client to your device.

Got it. Thanks.
