Lost access to global admin account

Question

Our company had a Microsoft 365 tenant in the past. Unfortunately, we lost access to the global administrator account and are unable to recover it.

We need assistance restoring administrative access. We have tried calling several support numbers and contacting multiple support email addresses, but none of them seem to be working.

Our company is considering purchasing licenses for the entire organization in the future, but the difficulty in reaching support is making us reconsider this decision.

Could someone please contact us to help resolve this issue?

Dear @Matěj H,

Welcome to Microsoft Q&A. 

I’m very sorry to hear about the situation you’re facing. Based on your description, I understand that your organization has lost access to the Microsoft 365 tenant because the Global Administrator account is no longer accessible, and you’ve been unable to recover administrative access through self‑service options. I also understand you’ve already tried contacting Microsoft Support through multiple phone numbers and email addresses without success.

Please allow me to clarify that Microsoft Q&A is a user‑to‑user support forum, and neither moderators nor community contributors have access to tenant back‑end systems or the ability to restore Global Administrator permissions directly. For security reasons, Microsoft does not allow Global Admin recovery to be handled through forums, email, or informal channels.

That said, I want to reassure you that I’ll do my best to guide you along the correct and supported recovery path, so you don’t lose more time trying ineffective options.

In scenarios like this, the only supported resolution is through Microsoft’s Data Protection team, who are responsible for verifying tenant ownership and restoring administrative access after proper validation.

You mentioned that you’ve already tried calling support. To make sure you are reaching the correct channel, I recommend trying again using the official Microsoft Global Customer Service phone numbers, selecting the options for a business account and technical support:

Please try to find the related hotline number to call the frontline let them raise a ticket for you: Customer service phone numbers - Microsoft Support 

In some countries, this is an automated conversation: First, when you call the hotline, they will ask you what kind of problem you are struggling with. 

Answer: Authenticator. 

A: What products do you use? 

B: Office 365 for business. 

Verification: Education or company account? 

B: For companies 

A: Are you an administrator? 

B: Yes. 

A: Are there any other administrators in your organization? 

B: No. 

A: I need one.... Service request? 

B: Yes 

 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. 

 

If you still cannot reach to agent, there is still a workaround, you might consider registering for a new tenant by signing up for a trial subscription via this link Compare All Microsoft 365 Plans | MicrosoftThis would allow you to create a new tenant following the provided prompts. Once set up, you can access the admin console of the new tenant and submit a support ticket requesting to speak with the Data Protection team on behalf of your previous tenant.  

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

I understand that this entire process can feel long and complicated, and I truly appreciate your patience while working through it. These steps are in place to protect the security of your account, so I hope you can understand why they are required. I sincerely hope you’ll be able to regain access to your account soon. If you need help at any point, or if you have any questions during the process, please feel free to reach out, I’m always here and happy to assist.  

Thank you again for your understanding and patience. 

Warm regards,
