once you have your corparate account set up, it should work properly - and no, it won't be as cheap.
Another caveat is that you may have mail issues if your mail account is a domain admin account. I have the same set up as you at home, and we don't have any probs, but we made the BB service account a domain admin, so I am suspecting that is why it works flawlessly. I haven't played with to find out for sure - if its not broke, don't fix it, right?
