The "Remove" link is unavailable when removing a domain from Office 365
Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.
When you try to remove a domain from Microsoft Office 365, you experience one of the following symptoms:
The Remove link is unavailable.
When you try to remove the domain by using Windows PowerShell, you receive the following error message:
Remove-MsolDomain : You cannot remove the initial domain created for you in Office 365. At line:1 char:18 + Remove-MsolDomain <<<< -DomainName <DomainName> + CategoryInfo : OperationStopped: (:) [Remove-MsolDomain], MicrosoftOnlineException + FullyQualifiedErrorId : Microsoft.Online.Administration.Automation.InitialDomainDeletionException,Microsoft.Online.Administration.Automation.RemoveDomain
This issue occurs if the domain is the Microsoft Online routing domain. The Microsoft Online routing domain is the domain that's issued to you by Office 365 (for example, contoso.onmicrosoft.com). This domain can't be deleted. Therefore, the Remove link is unavailable.
