Just because your company calls it a business phone doesn't mean Microsoft considers it one. From the beginning, MS unapologetically marketed Windows Phone as a consumer phone. They focused on personalization, user-friendliness, and social features but neglected business features like VPN support, encrypted email, mobile device management (WP7 didn't even support encrypted storage at all), and attachment support (although you can attach Office documents from within the Office hub).
Updates and new releases have slowly improved this area, and future versions will improve on it further (S/MIME encrypted mail and mobile device management are both said to be coming this year, along hopefully with VPN and better WiFi security options) but to call WP a business OS at this point in time is silly. It's a personal, consumer OS that has support for some business features, much like iOS was a few years after its initial release.

Do not private message me with questions that should have been posted on the forum!
Not only are you wasting your time - I'm not going to bother writing an answer to such a question for only one person - but I will probably block you from PMing me in the future as well.
