How did the device get activated on the BES? Did your IT guy plug it into his computer to start the activation? I'll bet he/she loaded the IT policy on the computer to fix a device and never removed it. Once on the computer it will install to every device connected to that computer.
It was either him/her or you. Are you sure YOUR computer doesn't have the IT policy on it? I would advise your IT person of the issue. You can remove the blank policy ("Method 2") by using "Method 1" of the thread below. Once you do that you'll need to reactivate on the BES. Your admin can give you a password to activate it over the air. You are better off starting with no IT policy, then when you activate on your BES you will get the proper IT policy. Let's hope that your BES isn't pushing my "blank" IT policy!
