Question

Need to authenticate to access admin, but can't ...

Nicola Graham 0

I have a M365 account, and I am the 1 user and admin for this account.

Whatever I click on, I'm asked to authenticate through my app, but the app doesn't work! I can't access the admin portal, or my account, via online console or the authenticator! Every single attempt sends me to the page of 'Verify your identity'. On the 'sign in another way' it only gives me ability to approve or use a verification code.

the help guides don't cover this from what I've read.

can anyone help me pleeeeease ...

Hi @Nicola Graham
In this situation, the official path to regain access is to contact Microsoft Support by phone for tenant recovery assistance.

I would recommend doing so, as it is often the fastest way to escalate tenant lockout scenarios. You can find the support phone number for your region here: Contact Microsoft Support

When calling the support number, you may first hear a recorded message lasting approximately 30 seconds (for example, suggesting that you visit an online support page). You can simply wait for the menu options to be presented. Typically, selecting "1" for business users and then "1" again for technical support will guide you to the appropriate support flow.

In some regions, the initial interaction may be handled entirely by an automated system. To help you prepare, below is an example of the questions you may receive and the recommended responses:

What kind of problem are you experiencing?

Answer: Authenticator

What product are you using?

Answer: Office 365 for business

Is this for an education or company account?

Answer: For companies

Are you an administrator?

Answer: Yes

Are there any other administrators in your organization?

Answer: No. I am the only administrator in the tenant.

Do you need a Service Request?

Answer: Yes. I need to open a support ticket. Please transfer me to the Data Protection team.

I hope this information helps you successfully escalate your request and regain access to your tenant. If you have any updates or additional questions, please feel free to reply to this thread. I will be happy to continue assisting you.

Hi @Nicola Graham

Please feel free to call them and use my script to bypass the SRV system. You can keep me updated here if you encounter any issues.

I hope you'll be able to resolve it soon.

Gosh this call service is laughable - it asks me questions, completely gaslights me and hangs up.

I have tried that and it literally just says random things back at me! This time I had 'please go to our website for help' ... I think handsdown the worst telephone experience I have ever had!

Hi @Nicola Graham

If you are unable to contact the Data Protection Team through phone support, you may consider creating a separate Microsoft 365 trial tenant and using it exclusively to submit a support request.

Here's how you can do it:

Go to Microsoft 365 Business Plans & Pricing | Microsoft 365 (select "Try for free" in an enterprise subscription).

Follow the instructions provided to create a trial tenant.

Once the new tenant is created, go to the Microsoft 365 Admin Center > Help and Support to submit a support ticket, requesting to speak with the Data Protection Team on behalf of your original tenant.

In the ticket description, you'll need to clearly explain that you're trying to regain access to your previous Microsoft 365 tenant as a single admin and that you need help from the Data Protection team.

Note:

This new trial tenant will not give you access to any data or settings from your original locked-down tenant. It only serves as a temporary means of contacting Microsoft support.

Remember to cancel the trial subscription of the new tenant once the issue with the original account is resolved, to avoid unwanted charges. Cancel your Microsoft business subscription in the Microsoft 365 admin center | Microsoft Learn.

I hope this helps.
