Hello

I'm trying to create a Microsoft services experience for my domain: unionjofficial.com

They're a UK-based music group and I'd like to use Outlook so I can set up custom email addresses. However I get the following message:
"This domain name can't be used because it contains a protected word or inappropriate language. Please contact support if you feel this is not the case."

Please could you rectify this?

Thanks
