Hello, i have a domain sternsystem.com which was recently added and active on Widows live admin center and was accidently removed. I am now trying to add the same domain at domains.live.com however I am facing problems in doing this. I have already deleted MX records in DNS setting of my domain and confirmed that is not there anymore but still I am unable to add my domain at domain.live.com. Following is the error I am getting :
This domain is already registered

This domain has already been registered with Windows Live Admin Center. You may register sternsystem.com with a new Live ID, but you must make the required DNS changes to allow you to make changes to the domain.
