Recovery of Admin account

Dear Microsoft Support Team,

I urgently need assistance recovering access to our existing Microsoft 365 business tenant associated with the domain stenum.at.

Our sole Global Administrator has passed away, and we no longer have access to the Microsoft 365 Admin Center or the administrator’s Microsoft Authenticator.

I am the Managing Director and owner of the company and can provide official documentation to verify my identity, my authority to represent the company, and our ownership of the domain.

Unfortunately, I have been unable to reach Microsoft Support through the usual channels. Telephone support directs me to an automated chatbot that terminates the call, while the online business support process requires me to sign in with the very business account that is currently inaccessible.

I am therefore requesting that this case be escalated to the Microsoft Data Protection / Tenant Recovery Team so that my identity and authority can be verified and administrator access to our existing tenant can be restored.

Please advise how I can initiate the recovery process without access to the locked business account and which documents or verification steps are required.

Thank you for your assistance. I would appreciate a response with a concrete next step for resolving this issue.

    Dear Christina Krenn,

    I am very sorry to hear about the loss of your colleague and understand the urgency of regaining administrative access to your organization's Microsoft 365 tenant.

    Based on your description, this appears to be a tenant lockout scenario where the sole Global Administrator is no longer available and no other administrator can access the tenant. In this situation, access generally cannot be restored through the community forum, and Microsoft must first verify ownership of the tenant before any administrative recovery actions can be considered.

    The recommended path is to contact Microsoft Support and request escalation to the Data Protection team. During the verification process, Microsoft may ask you to provide evidence that you are authorized to represent the company and that your organization owns the affected domain (stenum.at), such as:

    • Company registration or business ownership documents
    • Proof of authority to act on behalf of the company
    • Access to the domain's DNS records for ownership verification
    • Subscription and billing information associated with the tenant

    Only Microsoft's authorized support teams can perform the ownership validation required for Global Administrator recovery. Community moderators and forum participants do not have the ability to verify ownership or modify tenant administration settings.

    You can try calling again and follow the promp as following below: Customer service phone numbers - Microsoft Support

    Here are some tips and an example of a prompt to help you navigate the IVR more effectively: 

    IVR: What kind of problem are you worried about?

    You: Admin account locked

    IVR: What kind of product do you use?

    You: Office 365 for business

    IVR: Does it count for education or business?

    You: For Business

    IVR: Are you an admin?

    You: Yes

    IVR: Do you have another administrator in your organization?

    You: No

    IVR: Need a service request?

    You: Yes

    This should help you connect with a live support agent who can help you directly.

    If you can't create a support ticket during the call, I recommend creating a temporary tenant account and submitting the support request from there. To create a new tenant, follow these steps:

    1. Visit Office 365 E3 - Enterprise Collaboration and Productivity | Microsoft    
    2. Select any plan and click Try for free.    
    3. Complete the setup to create a new tenant.    
    4. Ticket support: In the Microsoft 365 admin center>support>help & support. You can create a support ticket: https://admin.microsoft.com/#/support/requests     

    Important: Please remember to cancel the trial subscription once your issue is resolved to avoid any charges.

    I hope this information helps and that you are able to connect with the appropriate support team soon.
