Error Code: 399287

Question

Hello, i have a ******@vlh5v.onmicrosoft.com admin account. And i cant sign-in because:

I’m unable to sign in to my work Microsoft account because of a multi-factor authentication (MFA) issue. My phone number from Kyrgyzstan is being blocked by Microsoft’s PhoneReputation service, and I receive no verification codes via SMS.

Here are the technical details:

• Error Code: 399287
• Request Id: ff4d3486-2140-41e3-ab6f-f41ccaf70e00
• Correlation Id: 7a5231f9-ec77-4ddb-be2e-67df124beda3
• Timestamp: 2025-05-18T19:38:45Z
• Region: Kyrgyzstan
• Mobile Carrier: [Beeline / Megacom / O!]

I have no backup MFA method configured (no Microsoft Authenticator, no alternate number or email), so I am completely locked out of my account and unable to access the Azure portal to open a support request myself.

Please escalate this case internally to the Microsoft Entra ID (formerly Azure AD) support team. I need help to either:

• Reset my MFA settings so I can set up new methods
• Or review and unblock my current phone number for MFA access

I kindly ask that you update me via email or any available method.

Thank you in advance for your assistance.
