Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello @Srdjan Andric,
I've reviewed your thread and I'm sorry to hear that you're locked out of the only business account of your company due to Authenticator.
Based on your description, you'll need to revoke your MFA access, which will allow you to set up Authenticator on a new device and then you can access Microsoft 365 admin center to change the payment method for your business account.
Please try to find the related hotline number to call the frontline and let them raise a ticket for you: Customer service phone numbers - Microsoft Support .
For Serbia, you can refer to:
Depending on your country or region:
For some countries, when calling the support number, although there are about 30 seconds opening as something "you can visit the link...." But you can ignore this opening and wait until the option, then "1" as a business email user, "1" again for technical help.
For some countries, it will be an automated conversation like:
- First, when you call the hotline, it asks what kind of problem you are worried about.
- Answered: authenticator.
- A: What kind of product are you using?
- B: Microsoft 365 for business.
- A confirmation: education or company account?
- B: For company
- A: Are you an administrator?
- B: Yes.
- A: Do you have the other admin in your organization?
- B: No.
- A: You need one.... Service request?
- B: Yes
If your subscription is from a partner or reseller, contact the reseller's support provider to help open a service request on behalf of you instead.
You may need to call multiple times before you are connected to a live support representative and can successfully create a support request with a ticket number for tracking.
If you still have trouble using the frontline support, you can try set up a new trial tenant and submit your support request:
- Visit the Microsoft 365 Enterprise Plans page: Go to Compare Office 365 Enterprise Pricing and Plans | Microsoft 365.
- Choose a plan and start a free trial: Select any of the available plans and click "Try for free" to begin the trial setup process.
- Follow the guided setup: Complete the steps to create a new Microsoft account and a new tenant. This will be a separate and independent Microsoft 365 environment.
- Access the Microsoft 365 Admin Center: Once the new tenant is created, navigate to https://admin.microsoft.com/.
- Go to Support:
- Click on "Help & Support" button like this image.
- Toggle Support Assistant option to OFF > Type your issue under "How can we help?" Box > click Get Help.
- The Contact Support button will become available, you can click on it now.
- Choose contact method: "Phone" or "Email"
- Raise a support ticket: Describe your issue in detail. Crucially, you must clearly state that you are locked out of a different, pre-existing Microsoft 365 tenant where you are the administrator. Provide the following information about your locked account:
- The domain name of your locked tenant
- Your administrator account.
- Any error messages you are receiving.
- Details about the authentication issues you are experiencing.
- Your proof of ownership.
- Finally, clicking on "Contact me".
Important notes:
- This new trial tenant will not give you access to any of the data or settings in your original locked tenant. It is solely a temporary means to contact Microsoft support.
- Be prepared for Microsoft support to ask for verification of your identity and administrative rights for the locked tenant.
- The resolution time might be longer as you are contacting support from a different tenant.
- Remember to cancel the trial subscription for the new tenant once your issue with the original account is resolved to avoid any unintended charges. You can typically do this within the Microsoft 365 Admin Center under "Billing" -> "Your products."
I hope you'll be able to reach the Data Protection team this way. If you still have any issue, please don't hesitate to reply. Wishing you a successful day!
