Creating initial tenant with preferred name

ritmo2k 706 Reputation points

I have a routable DNS name that I intend on using (, I also previously signed up for a trial (thinking it was decommissioned) so I signed up for a new one and have upgraded it to pay-as-you-go.

The new one has as the service address and I want

I decommissioned the original tenant to free up the preferred address and added it to my new tenant. However, I cannot remove the initial name.

I don't want my name in the service address as this is for my company. How can I resolve this?

    Thank you for your post and I apologize for the delayed response!

    From your issue and screenshot, I understand that you're trying to keep your Primary domain and remove the domain from your Azure AD domain list. Unfortunately, once the domain is added, it can't be removed. For more info.

    Note: Azure Active Directory (Azure AD) tenants come with an initial domain name, <domainname> You can't change or delete the initial domain name, but you can add your organization's names.

    You can't remove your domain. Microsoft 365 needs to keep it around because it's used behind the scenes for your subscription. But you don't have to use the domain yourself after you've added a custom domain. If you choose to create a new domain, it cannot be removed. You are limited to five domains in your Microsoft 365 environment, so make sure to check for spelling and to assess your need if you choose to create a new one.

    Our engineering team is currently aware of this limitation and has a backlog item to look into this.

    I hope this helps!
