Hi @Frank de Groof,
Thank you for reaching out to Microsoft Q&A forum.
I understand you’re having trouble verifying your Office 365 account, even though it’s currently active.
The message “Your account has not been verified. Please try again” typically appears during Microsoft Entra ID (Azure AD) multi-factor authentication (MFA) sign-in. This usually means the sign-in requires MFA, but the verification method on file cannot complete successfully. Common reasons include:
- Text or call not received
- Invalid or outdated phone number
- Method no longer allowed by your organization’s policy
- Account partially registered or reset
If you’ve tried both SMS and phone call options to verify your account and still cannot complete verification, please contact your IT administrator to request an MFA re-registration. You can share this Microsoft article with them for guidance: Manage user authentication methods for Microsoft Entra multifactor authentication.
Once your organization’s IT administrator has reset MFA for your account, the next time you sign in, you will be prompted to set up the Microsoft Authenticator app again from the beginning by scanning a QR code. This process will resolve the issue and allow you to access your account normally.
Please note that forum moderators do not have access to user account settings and cannot assist with logging in, resetting passwords, or changing access rights. While we do not have access to internal systems or administrative tools required to resolve account-specific or backend-related issues but we’ll continue doing our best to support you within the scope of our responsibilities.
I hope this helps you regain access to your account quickly. I'm glad to assist and truly hope the information provided has been useful. Please feel free to reach out anytime if you need further assistance.
