Adding a Subdomain Problem

Hello,

 

we have problem adding a subdomain to our environment. It is a ADFS enviroment and we have added the Domain always via PowerShell  -> New-MsolFederatedDomain.

 

If we add a specific subdomain we get the following error. 

 

 

Any other subdomain within the root domain works without any problems. 

 

What does this mean, has somebody setup a O365 environment and this is an unmanaged azuread with this subdomain and do we have to do an admin takeover ? We have found some blog posts about this. 

 

Many Greetings

Erik
