not provided
Scenario
Attempting to purchase new Microsoft 365 Business Basic licenses using various browsers, devices, and administrator accounts.
Observed behavior

Solution 1Recommended

Contact Microsoft Support to Lift the Automated Security Block

Reach out to Microsoft Support via the Admin Center to manually clear the backend security flag causing the E6118 error.

Error E6118 is triggered by Microsoft's automated security monitoring system, which occasionally flags and blocks legitimate payment attempts. Standard troubleshooting steps, such as changing browsers, devices, or network locations, will not resolve this backend restriction. Direct intervention from a Microsoft support agent is required.

Frequently Asked Questions

Why does error E6118 happen when buying Microsoft 365 licenses?

Error E6118 occurs when Microsoft's automated security monitoring system incorrectly flags and blocks a legitimate purchase attempt during the payment-method verification process.

Will using a different browser or credit card fix the E6118 error?

No. Because the error stems from a backend security block on your tenant or account profile, changing browsers, devices, locations, or credit cards will not resolve the issue. You must contact Microsoft support to have the block lifted.

How long does it take for Microsoft to lift the E6118 purchase block?

Resolution times vary once you submit a support ticket through the Microsoft 365 admin center. Typically, support agents can verify your tenant details and clear the automated security block within 24 to 48 hours.

Can a regular user contact support for this billing error?

No, you must have Global Administrator or Billing Administrator privileges in your Microsoft 365 environment to access the billing support section and log a ticket in the admin center.
