So my wife dropped her 950 face down and the screen shattered to bits, and it won't even turn on. So as a backup, I went out and got a 640 from Best Buy for $29.99. In setting it up I might have made the mistake of trying to restore her 950 backup, before remembering that the 640 was still on 8.1. So I downloaded the insider app and got 10 on there, but now somehow her outlook and contacts are gone, and every time I try and open the outlook app, it prompts to be setup. I am guessing I will have to "do over", but I'm wondering whats the best way to go about it. Reset the phone (which I am assuming will take it back to 8.1), start again, but do not restore, update to win 10, and then is it possible to restore?
