Now All I have is my @outlook.com alias account and I can't access the @live one anymore

When I try to sign in it says it doesn't exist... and when I try to create a new one using the same name that 'supposedly' doesn't exist... it says that the domain name isn't available!!!! What can I do!??

Also the troubleshooter says:

Unable to automatically fix the issues found:

Problem with Microsoft account policy      (Not Fixed)
