How to fix issue with not receiving ANY notifications in Authenticator app

Irene Kral 0

For a couple of months now, I am trying to login to my account. Not this one. I created this one, because I can only ask questions if I am logged in, and if I cannot log in, I cannot ask questions, and if I cannot ask questions, I resolve my issue. I hope ANYBODY can understand how FRUSTRATING this is.

However, I am trying to connect to my business account. I am confused with the email address, so I have the business address and also an onmicrosoft address. I am not sure which one to use, I am using the onmicrosoft address. I am reaching the following screen:

it just says I should type the code that shows in the Microsoft Authenticator app on my mobile phone.

On my phone there is NO code. Actually that is not true, I can see an 8 digit number called one time password code, but not under the selection xxxxxx.onmicrosoft.com but under another selection with the company email.

I am choosing another method.

Although within the app, I am refreshing as there were no tomorrow, nothing shows up.

there is also the option check for notifications, but it does not help.

Today I did something new (which I cannot find at the moment) that said should clean the phone notification cookies, which I did, but it did not help.

Can ANYBODY PLEASE PLEASE help me a way out of this non human support cycle. I really need somebody to understand my problem and advise what to do.

This nonsense FAQs and bot phone support is driving me crazy.

Thanks.....

Hi @Irene Kral

Regarding your issue, may I kindly ask a few questions to help understand it better?

Which exact email are you using to sign in? (@onmicrosoft.com or your custom business email?)
Have you changed phones, reinstalled Microsoft Authenticator, or removed/re‑added accounts recently?
Are you the tenant’s global admin or is there another admin who can reset MFA for this account? If yes, you can ask them to either unblock your account or reset your multi-factor authentication (MFA) for you.

They can follow these steps:

Sign in to the entra.microsoft.com as at least Authentication Administrator.
1. Select User -> All user. Select the user (your account) to act on and select Authentication methods. then select Require re-register of multi-factor authentication.

Require re-register MFA: This disables all previous authentication methods. You'll then be prompted to configure a new MFA authentication method the next time you try to sign in, so you can set up from the start and add a new authenticator app.

For more details, please refer to: Manage user authentication methods for Microsoft Entra multifactor authentication.

Note: Once re-registration is triggered, all your existing MFA methods such as phone numbers, Authenticator app, or other verification options will be removed. You will need to set up new MFA methods during your next login. Please ensure you have access to a valid phone number or the Microsoft Authenticator app before attempting to sign in again.

Hope to hear back from you soon. 

The initial response may not fully address your needs, but it will help me better understand your situation. Once I get the information, I will try my best to find the next steps.

Hello Jess, thank you so much for your answer.

Here are my comments:

Using the onmicrosoft account, not my business email.

I have not changed phones, reinstalled authenticator or changed accoutns.

This is a small business, we do not have any admins etc. its just me actually.

Microsoft entra admin center, never heard of it before

however, I have not been able to do a payment for two months, so my account invoice is 2 months overdue, this might be an additional issue (the login did not work even when the invoice was not overdue yet).

What I actually need is somebody to know how to contact support over the phone.

I cannot spend hours and hours and hours and hours reading and writing and not find any help.

Hoping for the best.

Thanks again

Irene

Hi @Irene Kral,

Regarding your issue, if you are the only global administrator and is locked out, the next step would be to contact Microsoft Data Protection team directly for assistance as they have tools and processes in place to verify identity and regain access to administrator accounts.

You can find the appropriate customer service phone numbers at this link: Customer service phone numbers.

Please remember to provide them with your account details and explain the situation. Be ready to provide:

The company name used during subscription

Billing email address (even if it’s a personal Microsoft account)

Payment method details (last 4 digits of the card, billing address)

Any subscription ID or invoice numbers from billing email

When you call the support number, you may hear an introduction of about 30 seconds such as "you can visit the link...". You can ignore this introduction and wait until you are presented with the options. Then press "1" as a business email user, and again "1" for technical help.

To make the process smoother, here’s an example of how to respond when speaking to the automated system (IVR):

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: 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

These prompts help direct your call to the right support team more quickly, especially when dealing with account lockouts and authentication issues.

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. This would allow you to create a new tenant following the provided prompts.

Follow the guided setup to create a new Microsoft account and a new tenant.

This tenant will be completely separate from your existing Microsoft 365 environment.

Once set up, you can access the admin console of the new tenant by logging into admin center and follow the steps in this article: Get support - Microsoft 365 admin and submit a support ticket requesting to speak with the Data Protection team on behalf of your previous tenant.

Include the following details:

The administrator email address for the locked tenant

The domain name of the locked tenant

Any error messages you are seeing

A description of the authentication or sign‑in issues

Confirmation that you are the administrator of the locked tenant

Before submitting the ticket, make sure the Support Assistant is turned Off as several customers have reported that when the Support Assistant is enabled, the Contact Support option may not appear.

As shown in the screenshot, simply switch Support Assistant > Off, then enter your issue description. Once disabled, the Contact Support button should appear, allowing you to submit the ticket normally.

Important note:

This new trial tenant does not provide access to any data, users, or settings from your original locked tenant. It is only intended as a temporary way to contact Microsoft Support.

Once the issue with your original tenant is resolved, be sure to cancel the trial subscription to avoid any unintended charges. You can do this from the Microsoft 365 Admin Center by going to Billing > Your products and canceling the trial there.

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

As forum moderators, we don’t have access to the detailed system needed to troubleshoot this effectively due to privacy and security constraints. To quickly resolve this and regain access, the most effective step is to contact Microsoft Support Team directly. Only they have the ability to help with your Authenticator issue.

Hopefully it will help work with your issue and if you have any other questions or need further assistance, feel free to ask.
