I had a video file on OneDrive that has somehow disappeared. Does anyone know who I can contact at Microsoft to get this file back ? I need it to give it to law enforcement, as it's of someone breakinto my bedroom and stealing a few of my item's. The person is on probation and I need the video to give to the probation officer. I used to have the video on my pc and backup drive. The files on my pc disappeared recently and the backup drive stopped working 2 weeks ago.
