Unable to login to windows 8.1 pro using Microsoft connected account.

Unable to login to windows 8.1 pro using Microsoft connected account.
User has somehow set up login to try and use email account as user name.
IE joe @xyz.com which is an Exchange service hosted on office 365.

I can login through the portal with user name and pass ,but the users computer says incorrect password when I try to login locally.

If I try to change pass in admin tools users ,it says The system is not authoritative for the specified account.
Any ideas?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

I am not sure what the user might have done to damage the ability to go backwards on the account.

Are you sure there is a local Administrator account?

If so, you should be able to reset this with Pogo Stick.

Make bootable USB key with this and then see if you can reset the password.
"The system is not authoritative for the specified account" - that message appears for any Microsoft account, it does not mean anything is damaged. Why you cannot use it to logon, I don't know. If there is a need to get into that very account, you could transform it back into a local account - that is complicated, but manuals exist.

So let me know: do you really need that very account or would you also be ok to create a new account that can access the data of that account?

Here's the exact message I am getting.
Doesn't matter if it's admin tools or command line using net user

That was clear before: it is a Microsoft account, you cannot change its password that way, but only as that user, when he's logged (which you are unable to right now) or change it online - that could be tried. Else, please answer my last question.

I ended up doing two things ,using a password changer from a 3rd party and somehow or other ,the user had created a M$ account with the same user name ,different pass(account.live.com).

The office portal was a different password although the user name was the same.
