I have a user that upgraded to Windows 8, and used his Hotmail credentials for Microsoft account synching. The issue is, when he typed his Hotmail email address in, he mistyped, and entered "firstname.lastname@example.org" with 2 of letter m in Hotmail. So now, when he boots computer, at login screen, it will not authenticate, as something is wrong with account. Windows wants him to resolve at providers website, and I can't create a user @ Hotmmail.com. I can log in as a different administrator, attempt clear / change his password, and Windows states that system does not have authority to do so, to use providers web site. I have used several password reset tools on <Admin Edit> boot disk, and they look as though it worked, but it does not. I can manually copy his data to a new profile, but was trying to avoid that. Any suggestions will be appreciated.
