Thank you for the update. So it says that the password ***** *****? Is the username a simple user name or does it show an email address?
On a working computer, are you able to sign into that account on the following page? --> https://login.live.com/
Are you entering the same password ***** the computer that you just entered onto that page to sign in?
That is very odd. If you used the same email address & password ***** the page and the login screen, it should be working.
I have run out of ideas.
For this reason, I am opting out of the question and allowing another expert the chance to help.
The next expert will see all that is on this page, so there will be no need to repeat anything.
When another expert picks this up, you will be notified by email.
Thank you for your patience.
You used the same email address on the problem computer login page and the page that I sent you a few minutes ago?
