Advanced Solutions for Persistent Issues

If self-service password reset is enabled for your account, use the “Can’t access your account?” link on the Microsoft sign-in page.

If recovery fails, double-check your entered details and retry. Ensure you use your correct email and up-to-date recovery methods. They can reset your password directly or provide further troubleshooting resources.
