I have investigated your account and it appears that your account is currently inactive. Please try to contact your domain admin about this issue.
Thanks for taking a look, unfortunately this is incorrect. I am the domain admin and all of our other domain accounts are working great. At some point this one was moved from just a Live (Microsoft) Account to have email capabilities. However, the mail
portion has never worked. This account is used for all of my billing use (or xbox.com, etc), except then when I try to log into outlook.com (or even other live.com assets) I will receive this error. This account is not the domain admin account although I
once was going to use it for that, which is why it might be confusing (i.e. domains.live.com shows an old domain registration there because this isn't the admin account for the domain).
There is something wrong with the way this account is registered, and based on how the URL redirects about 10 times while trying to login to outlook.com before failing it would appear there is something in an invalid state.
Can you please take another look? It would appear that your above investigation is incorrect.
Thanks
