Question

Release my domain from a dormant tenant I created and can no longer access

Stephen Kreyenbuhl 0

I need a domain released from a Microsoft 365 tenant that I created myself and can no longer sign in to. I am not asking to have administrative access restored. I only need the domain removed so it is no longer claimed.

Domain: kreyenbuhl.com

Tenant ID: [Moderator note: personally identifiable Information removed]

Default domain: kreyenbuhl.onmicrosoft.com

I created this tenant on 6 March 2024 through a free trial. The Microsoft 365 Business Standard subscription under it was cancelled on 8 April 2024. The tenant has been dormant since, with no licences and no activity. Cancelling the subscription did not release the domain, so the claim has persisted for over two years.

The only administrator account is [Moderator note: personally identifiable Information removed]@kreyenbuhl.onmicrosoft.com. That account still exists in the directory, but self-service password reset reports that the username does not exist, which I take to mean no authentication methods were ever registered against it and the tenant has held no licences since cancellation. There is no self-service route back in.

To pre-empt the obvious suggestion: I also hold a personal Microsoft account at [Moderator note: personally identifiable Information removed]@kreyenbuhl.com. It is on the consumer identity provider, it is a different identity from the directory account above, and signing in with it returns AADSTS50020. The tenant is fully managed, not unmanaged, so internal admin takeover does not apply either.

I have owned kreyenbuhl.com continuously since 7 June 2005 and I control its DNS. I can publish any TXT record, at any hostname, with any value, on request and within the hour. Microsoft has previously verified my control of this domain by exactly that method. I can also provide registrar records and the Microsoft notification emails for both the trial creation and the cancellation.

Could a moderator please engage the Data Protection team to release kreyenbuhl.com from tenant [Moderator note: personally identifiable Information removed]? Closing the tenant at the same time would be welcome, as nothing depends on it.

Hi Stephen,

To reach out to Data Protection Team, you can find Microsoft's support numbers here:

Customer service phone numbers: Contact Microsoft customer support | Microsoft Support

When contacting Microsoft, be prepared to verify ownership of the subscription. You may be asked for information such as:

Organization name
Billing or payment information
Registered phone number
Alternate email address

Once your identity is verified, you can proceed with request to remove your domain.

Tips for navigating the IVR:

In some countries, an automated voice system is used. Example of a dialogue:

IVR: What problem is bothering you?
Client: Lost access to the only admin account
IVR: What product do you use?
Customer: Office 365 for business
IVR: School or Business Account?
Client: Companies
IVR: Are you an administrator?
Client: Yes
IVR: Is there another administrator in your organization?
Client: No. I am the only admin in my tenant
IVR: Do you need to create a support ticket?
Client: Yes. I need to create a ticket. Please send me direct to the Data Protection Teams.

I also recommend calling during business hours. In my experience, it can be difficult to get through to the correct support queue, and automated systems don't always work as expected. If you can't get through on your first try, I suggest trying again later or at a different time.

In case you are unable to contact the frontline support:

Consider signing up for a trial subscription to create a new tenant. Once set up, you can access the new tenant's admin console and submit a support ticket to speak with the data protection team on behalf of the previous tenant. Once your issue is resolved, please remember to cancel the trial subscription to avoid any unintended charges.

If your organization's subscription is from a partner or reseller: Contact the reseller's support provider to help open a service request on behalf of you instead.

I hope this helps point you in the right direction. If you have any updates or additional questions, feel free to reply back and I'll do my best to assist further.

Thank you Ivory — the IVR walkthrough is genuinely useful and I'll work through it.

Two notes for anyone from Microsoft who picks this up.

First, moderation has redacted several identifiers from my original post as personally identifiable information. They aren't — they are tenant and directory identifiers: a tenant GUID, an .onmicrosoft.com default domain, and an administrator UPN. All of them are returned by unauthenticated Microsoft endpoints to anyone who asks, and none of them identify a person. Their removal makes the request harder to act on, since the tenant can no longer be identified from the post. I'm happy to supply all of them again directly to anyone from Microsoft who needs them.

Second, on similar threads here a moderator has engaged the Data Protection team through an internal support ticket on the poster's behalf. That is what I'm asking for. I am not requesting that administrative access be restored — only that the domain be released from the dormant tenant so it is no longer claimed. I own the domain, I control its DNS, and I can publish any TXT record you name, at any hostname, with any value, within the hour. Microsoft has previously verified my control of this domain by exactly that method.

If a phone call is genuinely the only route, I'll make it. But if a moderator can open the ticket from here, that would be a great deal more reliable than an IVR queue.

Hi Stephen,

The IVR system is recommended based on user experience data to help route calls efficiently. I'm glad you found it useful.

Regarding your ticket, from my experience, moderators on the forum are unable to create support tickets on behalf of users directly. To work around this, you have to either submit the ticket directly from your end through phone system or set up a new trial subscription for your old tenant.
