This would be a company that has registered for an office365 account. Office 365 company accounts are registered as companyname [dot] onmicrosoft [dot] com. You then add domain aliases if you want to use your own preferred domain name.

Is there a registry we can search to find the company behind a certain $domain [dot]onmicrosoft[dot] com domain?

Thanks,
