I am currently running the redirector on my desktop. It is sending all my mail from my outlook mailbox to my BB. My company is running Exchange 2000 for email. This setup works great and we are not running BES. The only drawback is that while I get my emails I can not reconcile over the air. The deletes and moves only take place once I plug the BB into the desktop and it syncs. Small price to pay for the convenience.
