AHH mate, if you have the option of returning the Surface, I would do that and get something else!!
My work has issued me one and it's absolutely awful!! I'm technically on my third one in less than a year as had so many issues in the first six months. They do not manage heat or power particularly well, especially when using it whilst it is on a soft surface (e.g in hotel room, sitting on a bed with it on your lap).
Regarding (new) outlook... It's still dog ****... Not just for auto capitalisation ... I hear because it's very much cloud based, it does not perform well at all.
I wish you luck!!
