Authentication error AADSTS50196
I may have a partial solution to AADSTS50196, at least it seems to have worked for me. Without being able to access any Microsoft information including account info, I was able to, after many dead ends, to find some account info. Apparently some time in the past I had a Microsoft account and I found that the phone # listed was not the same as the one I used to set up my new computer. I had the option in front of me to delete the old number and enter the correct number. What followed was a long and tedious process that necessitated two password change, several texted codes, and six or eight e-mailed codes. Now I can actually sign into my Microsoft account
Greg-_600 To verbalize the flash of inspiration I had: When the Microsoft system encounters conflicting data, it will reject both because computer systems connote determine which is true and which is not true. I think that this is likely to be the case for those who are chronically plagued by AADSTS50196
