How do I delete the BlackBerry Enterprise Server e-mail from my account?

Here's the thing. I set up my blackberry with an address e-mail from work using the Enterprise server, it is validated and everything seemed ok. But I'm still not receiving emails, it seems that I should have set it up at bit other where you can just type an e-mail (my company is to allow this). Now I can not change the e-mail BES just bring my provider e-mail on the BlackBerry setup screen e-mail. Does anyone know how I solve this?
