Diabolical I've been using Microsoft one drive and other Microsoft apps for years now and never had an issue until I had to move house last year and couldn't take my services with me due them not serving my area. I had to change my mobile phone number and my old one got disconnected, I now can't sign in to my one drive account and lost precious photographs, private documents and other things as I have lost the password, no help or support from Microsoft whatsoever.
