Maybe try turning off saving your sent messages on your PC.. Not sure if it will work, but it's worth a try. I don't use outlook though, just tossing out an idea.

go to the verizon BIS login page and set up the filter so that your phone does not receive emails from your email address. It is quite simple.
Have you ever been to this page? If not, then I am assuming a tech in store set up your BB for you. Hopefully, you received your account information from them. If not, call Verizon and get the login information from them. You can also click forgot password and enter your PIN. That is assuming you know your login name.
