I run 6.5.5 servers with Groupwise 7.0.2 (on one by itself) and nothing special.

I know nothing about this procedure, My question is what does it take "software wise" to get a blackberry to work?

What is "BlackBerry Enterprise Server software" ? What is the cost?
Does it require its own server?
What is involved with getting devices to run on this.

If anyone could point mr toward a procedure or explicid documentation it would be appreciated.
