I have an 8700 G with T Mobile service on a BB Server through corporate office. I am a newbie with this device. I want to see HTML email on the BB but when I open the message all I see is links. How do I set the client to read HTML email?

You need to read this:

Welcome to the BBF.

I have been using the Empower software to assist in viewing HTML messages. It is probably the best solution so far (at least that I have seen)

I agree with John and JBairdJr. Empower HTML viewer is the slickest product out there. I stongly recommend the Pro version 3.0 . It is significantly faster than the earlier version and works better in general. .. 73

I believe that you will eventually get it with os 4.5...eventually
