Remove a domain from Office 365

If you are having trouble removing a domain using the Office 365 management portal you can use the Microsoft Online Services Module for Windows PowerShell to help.

First off download the module and find out a little bit more about the MSOL module from here,

Use the following cmdlets to connect, identify and remove domains.


the following command will list the domains you have added to O365.

Change the default domain.
Set-MsolDomain -IsDefault -Name

Remove the domain.
Remove-MsolDomain -domainname –force

Hope this helps, it worked for me out moving domains between tenant organisations and not getting any response to my “service requests”.
