My domain (megawattnrg.com) is registered both with domains.live.com and with outlook.office365.com.  When I try to add a user account to my windows 8 PC using my company's domain name, it gives me an error saying 'this email address is part of a reserved domain such as live.com, Hotmail.com or msn.com. Please use a different address.

Am I having this problem because my domain is registered with both services?

How does one delete the domain from domains.live.com?  When I try to manage my domain logging into domains.live.com, it says my domain is already registered with Microsoft and that I need to contact support.  I have gotten no where when trying to seek help so far....

Any help would be most appreciated.

Thanks,

Walt
