Unable to Set Up Microsoft Account Due to Old Tenant ID

Question

Unable to Set Up Microsoft Account Due to Old Tenant ID

CGAM 0

Hello Microsoft Support,

I am trying to resolve an issue with setting up a Microsoft account connected to a domain I have registered through IONOS.

IONOS investigated the issue and advised me that Microsoft has confirmed the problem is because my domain is still associated with a tenant ID from a previous Microsoft account.

They advised me to contact Microsoft directly and request that the old tenant ID linked to this domain be removed or released, so the domain can be used properly again with a new Microsoft account.

The difficulty is that I do not currently have access to any Microsoft products, Microsoft 365 admin centres, or an active Microsoft account that would allow me to raise this issue through the usual admin support route.

IONOS gave me a Microsoft phone number, but it does not appear to be the correct route for this particular Microsoft tenant/domain issue. I was then directed to raise a ticket, but I have ended up here on the Microsoft forum instead.

Could someone please advise the correct Microsoft support route for resolving this? Ideally, I would like Microsoft Support to contact me through a secure/private channel so this can be handled properly, as I do not want to share my domain name, account details, tenant information, or any personal information publicly.

The domain is registered with IONOS, and the email/account service involved was Microsoft Outlook/Microsoft 365.

Thank you.

Hi CGAM

Based on your description, this appears to be a domain ownership/tenant association issue, where the domain is still linked to a previous Microsoft 365 tenant. Requests to release or remove a domain from an existing tenant require verification by Microsoft's support teams and cannot be processed through the Microsoft Q&A forum.

Please understand that we're not Microsoft support, this is a user-to-user support forum. Moderators do not have access to tenant information or backend systems. We provide only technical guidance and best-practice recommendations based on reported issues.

You mentioned that you were directed to raise a support ticket. May I ask whether a support case has already been created with Microsoft Support, or were you advised to create one but have not yet been able to do so? If a support case has not yet been created, you may to contact Microsoft Customer Service again and explain that this is a domain ownership/tenant association issue requiring assistance from the appropriate Microsoft support team.

When you contact support team via phone service number: Customer service phone numbers - Microsoft Support, the agent will be able to create a ticket for you under the affected tenant and then transfer this ticket to Data Protection team who could help you to regain access.

During the call, the first step is to provide an automated voice response from AI. Be careful, you won't be able to speak to a support representative if you don't respond appropriately here.

Here's an example of a response that actually led to a support representative. Please refer to it.

In the meantime, you can go to aka.ms/m365profile and file a case online. If you prefer, you can also text the link to the phone number you are calling. What do you think? 
A. The phone number is already linked to the link. 
Q. Can you tell me about the products in your inquiry? 
A. Microsoft 365 Business Standard. 
Q. Are you a Global Administrator? 
A. That's right. 
Q. I'm sorry. I didn't understand. Are you a global administrator for your domain? 
A. Yes, I am a global administrator for the domain. 
Q. If you have any inquiries, you can contact a Microsoft representative. Are you sure? 
A. Yes. Please.

Please note that this team is always overwhelmed, so you might need to wait for them to call you, this should take 3-10 working days.

In case the phone line is not supportive, you can consider directly submitting a support request as a helpful workaround:

Create a temporary Microsoft 365 tenant using a trial license: Go to Microsoft 365 Business Plans and Pricing and click Try for free to set up a temporary Microsoft 365 tenant with a trial license.
Use this new account to sign in to the Microsoft 365 Admin Center and submit a support request on behalf of your primary (locked) account.
Click Help & Support > then choose Create a support request.

Note: This method doesn't require you to use your new account for your business. Instead, it allows you to create a temporary global administrator account so you can submit a support request. The trial account is free for one month. Be sure to delete it after submitting your support request to avoid any automatic renewals or charges from Microsoft.

For further instructions, you can follow this guide: Get support - Microsoft 365 admin | Microsoft Learn.
