Dear @SVT kompiuteriai,

I’m very sorry that you’re experiencing this situation after replacing your phone.

When you change or replace your device, Microsoft Authenticator does not automatically transfer MFA settings unless cloud backup was previously enabled and then restored on the new phone. Since the Authenticator app was reinstalled without a backup, the original MFA registration is no longer available, which is why the verification codes are not being accepted.

Because you are the only Global Administrator in your tenant and there are no alternative authentication methods or additional admins configured, this situation is considered a tenant lockout. In this scenario, the Microsoft Data Protection team is the only team authorized to verify tenant ownership and assist with resetting or re‑registering MFA for the affected Global Admin account.

Please also note that this forum is a user-to-user support space. Forum moderators do not have access to user accounts and are unable to reset passwords, change authentication methods, or intervene in sign-in issues.

I found a contact number for Lithuania, you can try calling this number or find the related hotline number to call the frontline let them raise a ticket for you: Customer service phone numbers - Microsoft Support

User's image

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 Office 365 Business subscription was purchased through a partner or reseller, and you’re unable to open a service request directly, you may also contact the reseller’s support provider and ask them to open a support request on your behalf.

If you still cannot reach a support agent, there is an alternative workaround. You can register a new Microsoft 365 trial tenant by signing up through the following link: Compare All Microsoft 365 Plans | Microsoft.

After the trial tenant is created, you’ll be able to access the Microsoft 365 admin center and submit a support ticket from there. In the ticket, clearly explain that you are locked out of a different, existing tenant where you are the only Global Administrator, and request escalation to the Data Protection team for tenant recovery.

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

I understand that this process can feel long and complicated, and I truly appreciate your patience while working through it. These steps are required to protect the security of your tenant and ensure that only verified owners can regain administrative access. I sincerely hope you’ll be able to recover access to your account as soon as possible.

If you have any questions along the way or need further guidance, please feel free to reach out. I’m always here and happy to help.

Thank you again for your understanding and patience.

Warm regards,

I know this Microsoft phone in Lithuania, this phone is useless: only recorded greeting is played, then few sentences in 8x speed and then they asks to enter extension number. What extension number is needed - there is no information. There is no options to start conversation or answer questions. I have been trying to contact Microsoft in Lithuania for over half a year now, but to no avail. There is only a sales representative here who can only sell licenses. You provide me copy-paste information from internet and what does not work in my country. I will try, maybe it helps, because I do not see other way to get support in this limitrophy. Anyway, too complicated solution and shows real Microslop attitude towards customers: "If you still cannot reach a support agent, there is an alternative workaround. You can register a new Microsoft 365 trial tenant by signing up through the following link: Compare All Microsoft 365 Plans | Microsoft.

After the trial tenant is created, you’ll be able to access the Microsoft 365 admin center and submit a support ticket from there. In the ticket, clearly explain that you are locked out of a different, existing tenant where you are the only Global Administrator, and request escalation to the Data Protection team for tenant recovery."

Hi SVT kompiuteriai,
I’m truly sorry that my previous reply did not feel helpful to you. I can see that you have already spent a great deal of time and effort trying to resolve this issue, and I fully understand how exhausting this situation has become for you.

Please know that I genuinely recognize how serious this is, when you are completely blocked from your own tenant and the available support channels feel unresponsive.

I would like to clarify, that in my role here I’m only able to guide, explain the situation, and share the available recovery paths based on Microsoft’s official processes. I don’t have access to internal systems, and I’m not able to reset MFA, bypass authentication, or open support cases on your behalf.

Because of the difficulties you’ve described with phone support, I sincerely recommend considering the trial tenant option as an alternative way to raise a support ticket and request escalation to the Data Protection team. I know this is not ideal, but in practice it has helped other customers break out of the support dead‑end when phone routing fails.

If you decide to go this route, I want to assure you that I will stay with you here, answering questions, clarifying next steps, and helping you understand what to expect during the process. I’m more than willing to support you through it as best as I can.

I truly hope you’ll be able to regain access to your tenant, and I’m very sorry that this experience has been so difficult. Please don’t hesitate to continue the conversation here if you need clarification or support along the way.

Kind regards,

Hi @SVT kompiuteriai,

Thank you for your reply and thank you for pointing this out.

I appreciate your understanding. I’d like to apologize for the confusion earlier, I responded to your previous message before it was edited, which caused a bit of misunderstanding on my side. Thank you for your patience in clarifying the situation.

I’m genuinely glad that the trial tenant idea was helpful to you, even though I fully agree that this is a far more complicated process.

Please know that I truly respect the effort you’ve put into trying to resolve this, and I’m very sorry that this situation has affected your trust and confidence, particularly when you’re considering Microsoft 365 for a larger deployment.

If you decide to proceed with the trial‑tenant approach and run into any questions along the way, or if you need help wording the support ticket so it reaches the Data Protection team as clearly as possible, please feel free to reach out here at any time. I’ll do my best to support and guide you through the process.

If this answer or the workaround turns out to be helpful, you may also consider marking it as the accepted answer. This can help other customers who face a similar tenant lockout situation, or who are unable to reach Microsoft support by phone in their region, to find this workaround more easily.

Thank you again for sharing your experience and for your understanding, despite how difficult this has been.

Kind regards,
