How to Update Microsoft 365 Billing When the Only Admin Is Locked Out
Question details
The sole Microsoft 365 administrator is locked out of the account due to outdated two-step verification details and needs to update billing information.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Trying to update payment and billing details while unable to log into the admin portal.
- Observed behavior
- The user is stuck at the two-step verification prompt because it sends codes to a previous phone number and former company email address, blocking access to the admin center.
Gather your organization's subscription details, previous billing invoices, and your domain name before contacting support, as you will be required to strictly verify your identity.
Contact Microsoft 365 Business Support via Telephone
Since you are the only admin and cannot use self-service password reset or MFA changes, calling Microsoft Support directly is the only secure way to regain access.
When the only global administrator for a Microsoft 365 tenant is locked out, standard self-service recovery options will not work. Microsoft's Data Protection team must manually verify your identity to reset your multi-factor authentication (MFA) settings.
Visit the official Microsoft 365 support phone-number page to find the specific customer service telephone number for your country or region.
Dial the number during local business hours. Explain to the automated system or support agent that the sole global admin is locked out due to inaccessible MFA methods.
Provide the agent with your tenant ID, billing details, subscription information, and domain name to prove ownership of the account.
Give the support agent an alternate email address or phone number so they can communicate securely with you during the account recovery process.
Switch to WPS Office for Hassle-Free Document Management
Dealing with complex admin portals and account lockouts can disrupt your workflow. WPS Office provides a lightweight, highly compatible alternative for your team's document, spreadsheet, and presentation needs without complicated subscription management.

- 2. Install the software: Run the setup file and follow the on-screen instructions to complete the installation in seconds.
- 3. Open your files: Launch WPS Office and directly open your existing Word, Excel, or PowerPoint files without needing an online admin account.
Frequently Asked Questions
Can I reset my Microsoft 365 admin MFA without calling support?
If you are the only global admin and your configured MFA methods (phone/email) are inaccessible, you cannot bypass it via self-service. You must contact Microsoft Data Protection support to verify your identity.
How long does it take to regain access to an admin account?
Because Microsoft takes tenant security seriously, the Data Protection team will need to thoroughly verify your organization's details. This process can take several days depending on how quickly you can provide proof of ownership.
Can I update billing details without signing in to the admin center?
No, billing and payment information can only be updated securely from within the Microsoft 365 Admin Center. You must restore your admin access first before you can modify any financial information.
