Question

Microsoft 365 admin became unaccusable - only global admin.

Devesh Ranjan 20

I am admin on a business account, and my authenticator app is not providing code. I did not have any other means to get the code, and I am the only global administrator on the account. Please let me know how I can get out of this situation.

Without the authenticator code I am not able to log in any application or able to get support.

Please need urgent help.

Dear Devesh,

Good day, and thank you for reaching out to the Q&A Forum. I'm truly sorry to hear that your Microsoft 365 admin account has become inaccessible because the Authenticator app is no longer providing a code. I can only imagine how urgent and stressful this must be, especially as you are the sole Global Administrator and cannot access the Admin Center to open a support request from within the portal.

As a forum moderator, I genuinely wish I could directly access your tenant to reset the MFA method for your Global Admin account. Unfortunately, my role here is limited to providing general guidance that users can apply themselves. I cannot bypass the security protocols or make any changes to your account.

For your situation, the right team to assist is Microsoft's Data Protection Team. They have the necessary tools to verify your identity and help you regain access to your account. The best way to reach them for a business account is by phone. You can follow this article to check global customer support phone number from your region.

Customer service phone numbers - Microsoft Support

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

In some countries, it is an automated conversation like: First, when you call the hotline, it will be asked as follows:

IVR: What kind of problem are you concerned about?

You: Authenticator

IVR: What kind of product do you use?

You: Office 365 for business.

IVR confirmation: education or company account?

You: For companies

IVR: Are you an administrator?

You: Yes.

IVR: Do you have the other administrator in your organization?

You: No.

IVR: Do you need a... Service request?

You: Yes, please connect me with the Data Protection Team.

Kindly note that you may need to repeat this process a few times, availability can vary based on local business hours, and the term "Global Admin" should be clearly mentioned during the call.

Alternative, you can create a trial tenant account and submit your request from there.

To set up a new tenant, please follow these steps:

Visit Compare Office 365 Enterprise plans and pricing, choose any plan and click try for free to start a free trial.
Choose any plan (e.g., Business Basic, Standard, or Premium) and click "Try for free" to start a free trial.
Follow the guided setup process to create your new trial account.
Once the new tenant is created, you should be able to access its support portal and submit your ticket.
Log in to the Microsoft 365 admin center (admin.microsoft.com).
Navigate to Show all > Support > New service request
In the request, explain your situation in detail.

The support team will guide you through the identity verification process to help you regain access to your account.

Important notes:

This new trial tenant does not grant you access to data or settings of your original locked tenant. It only serves as a temporary way to contact Microsoft support.
Be prepared for Microsoft to want to verify your identity and administrator privileges for the old tenant.
The processing time may be longer because you are contacting support from another tenant.
Remember to cancel the trial subscription as soon as your original account is restored to avoid unwanted charges. You can do this in the Microsoft 365 admin center under Billing > Your products.

I truly hope you get your issue resolved swiftly. Please know that even though I can't directly intervene, directing you to the correct, specialized support is the most effective help I can provide from my position. Should you have any further questions or need additional assistance, please don't hesitate to reach out. I'm always happy to help. Wishing you all the best.

Thank you, I followed your steps and created a new tenant and through support, created a service request. How long will this take for the ticket to be addressed, any idea.

Expect response within: 8

Expect response within: 8

This is what I see in the ticket, not sure what is number 8 representing. Is it hour or days?

Dear Devesh,

Thank you for your update.

I have checked on your ticket, and the "Expect response within: 8" value you are seeing refers to 8 hours, not days. This means a Microsoft support agent should reach out to you within approximately 8 hours of the ticket being submitted, either by phone or email, depending on the contact preference you selected when creating the request.

A few things to keep in mind while you wait:

The response time can vary slightly depending on the time zone and the support team's local business hours.

Please keep an eye on both your email inbox and spam / junk folder, as the first reply from Microsoft sometimes lands there.

If you provided a phone number, make sure your phone is reachable, as the agent may attempt to call first.

If 8 hours have passed without a response, you can sign back into the new tenant's Admin Center and check the ticket status, or follow up directly from there.

Once you are in touch with the support agent, please be ready to verify your identity and provide:

The original tenant domain and your admin email address.

Any proof of administrator privileges (for example, billing or payment records, original setup email, or domain ownership proof).

This will help the engineer move the recovery process forward as smoothly as possible.

Also, if the answer was helpful, please consider clicking “Accept Answer” and giving it an upvote. This small action can help other community members who may run into a similar situation in the future.

Please feel free to come back and let me know how the support call goes. Wishing you a smooth resolution and all the best.

I was called on this ticket on 26th Friday and I was out of office. Yesterday I created another ticket still waiting to get an answer. I made several attempt to contact the assigned support, but none was answered. Then I decided to create a new ticket referring to the older one. I am on US ET and looks like I get contacted after hours. There is absolutely no traction on all the requests and timelines and information I have been adding on these tickets.

New Ticket #****[Moderator note: Personally Identifiable Information removed]

Old Ticket #****[Moderator note: Personally Identifiable Information removed]

This is such a stalemate I do not know how to get out of this and be able to perform my work and admin work. Any direct phone call totally blocked by AI, the AI agent takes all the information and then simply drops the call.

Wondering if this is how the Microsoft support works always, I am relatively new customer, less than a year when I moved from google suit to Microsoft 365. Never faced this kind of issues. Also, Microsoft 365 never alerted me with my admin setups, or I got any instructions to set the account so that such situations would not arise. There was absolutely no onboarding. Google did much better in this respect. I am so disappointed with the Microsoft 365 support service.

Dear Devesh,

Thank you for the update and for sharing both ticket numbers, this really helps me look further into your case.

I have checked on both tickets from my side, and I can see that two support agents have already been assigned, one to each of your tickets, and have attempted to reach out. Unfortunately, the call attempts have so far not been able to connect with you.

To help the support agents move your cases forward as quickly as possible, I would recommend replying to the support email thread with as much detail as you can provide upfront, such as:

Tenant ID

Domain name

Affected user's username (UPN)

A short, clear summary of the issue

Best contact phone number and time window (e.g., "Available 10 AM - 4 PM US ET")

The more complete and concise the information you can share in your reply, the easier it becomes for the agent to act on your case without needing to go back and forth for clarification.

Also, please double-check your spam / junk folder, as the first contact email from Microsoft Support sometimes lands there.

I also want to gently share one important detail about how Microsoft Support call attempts work, the phone connection is one-way, meaning only the assigned support agent can call you, and there is no direct number for you to call them back. However, you can still reach the agent at any time by replying to their support email thread, which is the most reliable way to communicate back and share additional information or updates from your side. Because of that, the best path forward is to make sure your phone and email are closely monitored during the next expected outreach window, so the agent can successfully connect with you.

I truly hope this gets resolved for you very soon. Please feel free to come back here with an update once the agent successfully connects. Thank you for your patience and understanding. Wishing you all the best.

Since I am unable to connect to the global admin account, I am not able to find the TennantID, not sure how else I can find that information.

Dear Devesh,

Thank you for the update. You can use the public Microsoft tool below to retrieve it just by entering your tenant's domain name: Tenant Lookup

Once you have the Tenant ID, please share it in your reply to the support email thread, along with the other details I mentioned earlier. That will give the support engineer everything they need to act on your case as quickly as possible. Please let me know if you need anything else.
