    Hello J Po,

    Greetings! Thanks for raising this question in Q&A forum.

    The error code 715-123420 typically indicates that the request was flagged by Microsoft's automated risk or abuse-prevention checks during the preflight validation stage of the Microsoft.CognitiveServices/accounts deployment. This is generally a service-side validation issue rather than a problem with the Bicep syntax itself.

    Please try the following steps:

    1. Verify that the subscription is active and does not have any spending limits, security restrictions, or compliance holds.
    2. Try deploying the Cognitive Services/OpenAI resource manually through the Azure portal in the same subscription and region to confirm whether the issue is specific to the Bicep deployment.
    3. Ensure the target region supports the Azure AI Foundry/OpenAI resource and model configuration being deployed.
    4. If the deployment continues to fail with the same 715-123420 code, open a Microsoft support request and provide:
      • Subscription ID
      • Deployment timestamp (UTC)
      • Correlation ID from the deployment error
      • The full deployment error details

    Since this error indicates the request was identified as unusual activity, Microsoft Support will likely need to review backend validation logs and determine whether a temporary restriction has been applied to the subscription. The next action is with the subscription owner or tenant administrator to engage Microsoft Support for further investigation.

    If this answer helps you kindly accept the answer which will help others who have similar questions

    Best Regards,

    Jerald Felix.
