Sounds like you need BES (Blackbery Enterprise Server) Otherwise you'll have to have the redirector running somewhere full-time while it's connected to the exchange server. If you do not have a desktop at your office, this could be a problem.

Another possibility, though not near as elegant is to have the exchange server forward mail to a BWC (Blackberry Web Client) email address. You could do this with server-side rules. The downside is when you reply you will be using the BWC email address and not your own corprate address.
