Error 715-123420 when deploying gpt-5-mini in Microsoft Foundry

I am using Microsoft Foundry for a Microsoft Learn AI fundamentals exercise.

I created a Microsoft Foundry project successfully. However, when I try to deploy the gpt-5-mini model using the default deployment settings, I receive the following error:

715-123420: Our system has detected this request as unusual activity for your account. If you are confident this is in error, please contact support.

I am only using this Azure subscription for learning and practice purposes, and I believe this may be a false positive.

I also tried to create a technical support request through the Azure portal, but my subscription currently has the Basic Support plan, which does not allow me to submit a technical support ticket.

Could a Microsoft moderator please advise how I can have this restriction reviewed or escalated to the appropriate internal team?

Thank you.

    Dear @Yeong Eun Kim

    This error isn’t caused by your deployment settings or the model itself. Error 715‑123420: “Our system has detected this request as unusual activity for your account” is a platform-level block from Microsoft’s automated fraud/risk protection (Real-Time Fraud Protection, RTFP) that intercepts Foundry/Azure OpenAI model deployments before provisioning.

    Because it’s an account/subscription safety review, changing model, region, SKU, or retrying won’t clear it; the restriction must be reviewed and lifted by Microsoft’s internal team.

    How to get this reviewed or escalated

    Even with a Basic support plan, you can still open a support request for subscription/account-level issues. Use the following steps:

    1. Open a support request in the Azure portal
      • Go to Azure portal → Help + support → Create a support request.
      • Issue type: Technical (or Subscription Management if that option is shown for account/risk flags).
      • Service: Azure OpenAI Service or Azure AI Services (whichever owns your Foundry resource).
      • Problem type: Account or subscription access (or closest equivalent like Subscription unblock or reinstatement).
    2. In the description, include:
      • The exact error text: 715-123420: Our system has detected this request as unusual activity for your account. If you are confident this is in error, please contact support.
      • Your Subscription ID, resource group, Foundry/AI resource name, region, and the model + version you’re deploying (e.g., gpt-5-mini)
      • The UTC timestamp of a failed deployment attempt.
      • Any IDs shown in the error or Activity Log: Trace ID, Client Request ID, Service Request ID, or Correlation ID.
    3. Explicitly request RTFP review
      • State clearly that you are hitting error 715‑123420 and ask for the case to be routed to the Fraud Protection / RTFP team for a manual review and unblock of your subscription for Foundry/Azure OpenAI deployments.
    4. While the ticket is open
      • Avoid repeatedly retrying deployments or creating/deleting Foundry resources; this can reinforce the risk signal.
      • Wait for support to confirm the restriction is lifted, then try a single deployment again.

    If the portal doesn’t let you create a “Technical” request due to Basic support, try creating a Subscription Management request instead (billing/account category), which is allowed on Basic plans, and reference the same error code and RTFP review request.
