Using this script you can test the domain availability in Office 365 and Azure AD. As there are different closed Office 365 and Azure AD regions you need to test per dedicated closed Office 365 region.
Regions currently implemented:
The script queries the login uri for the selected Office 365 region.
The response contains metadata about the domain queried. If the domain already exists in the specified region the metadata contains information if the domain is verified and/or federated.
