Unable to deploy claude models in microsoft foundry

Swati Singh 0 Reputation points

Hello,

I recently tried deploying Claude models on my Microsoft foundry resource but they are stuck on creating... forever and then fail after trying for an hour. I can easily deploy other models like DeepSeek V4 Pro, but not any of the Claude models. On old version of foundry, I get to know that the error code is 715-123420 which corresponds to Microsoft's real-time fraud prevention flag. I want Microsoft to manually review my account and further unblock it so I can use Microsoft foundry normally.

Will appreciate support.

Thank you

    Hello @Swati Singh ,

    Welcome to Microsoft Q&A .Thank you for reaching out to us.

    Thank for sharing the detailed information and observations.

    The observed behavior indicates that the failure is occurring during the provisioning phase rather than at the model execution layer. When deployments remain in a “Creating” state for an extended time and then fail ,especially when no Marketplace-backed Microsoft.SaaS resource is created ,it strongly suggests that the issue is occurring during the Azure Marketplace SaaS fulfillment and partner onboarding process.

    Claude models rely on successful Marketplace subscription creation and backend linkage, and if this process does not complete, deployments cannot succeed even when all visible configurations appear correct.

    The presence of error code 715‑123420 is typically associated with platform-level validations or subscription-level restrictions that require internal review.When such validation is triggered, repeated retries, region changes, or configuration updates do not resolve the issue until backend verification is completed.

    Please review the following before proceeding further-

    1. Subscription and billing:
      1. Supported subscription type
      2. Active billing method available (not credit-only)
    2. Region validation: Deployment attempted in supported regions such as:
      • East US 2
      • Sweden Central
    3. Permissions: Owner or Contributor access available on the resource group
    4. Marketplace readiness:
      1. Marketplace purchases enabled
      2. Required providers registered:
        • Microsoft.CognitiveServices
        • Microsoft.MarketplaceOrdering
        • Microsoft.SaaS

    To further confirm the scope of the issue, the following validation steps will be helpful

    1. Attempt deployment of multiple Claude models (such as Sonnet or Haiku).If all fail, it confirms a partner onboarding issue
    2. Attempt deployment of a non-partner model . If successful, it confirms the issue is isolated to Claude onboarding

    Additionally, it is important to verify whether there has been any recent subscription, tenant or resource movement. Anthropic deployments depend on backend identity mapping tied to these attributes and any change may lead to failures specific to Claude models while other models continue to function. In such cases, creating a new Azure AI resource and redeploying is often required.

    Hi Swati Singh,

    Welcome to Microsoft Q&A,

    The fact that other models (DeepSeek) work fine but Claude fails is a key clue here. This points to a Claude-specific deployment block rather than a general Foundry issue.

    Why does error 715-123420 happen specifically for Claude

    Unlike most models, Claude models are deployed through Azure Marketplace (Anthropic is a partner publisher). This means your Azure subscription goes through an additional Marketplace billing validation during deployment. The fraud prevention flag gets triggered at this layer, not at the Foundry layer.

    Check these first:

    1. Subscription type compatibility

    Claude models have stricter subscription requirements. The following are not supported:

    • Free trial or student subscriptions
    • Azure sponsored/credit-only subscriptions
    • Cloud Solution Provider (CSP) subscriptions
    • Enterprise accounts in South Korea

    You need an active pay-as-you-go subscription with a valid payment method on file.

    2. Azure Marketplace access

    Verify that your subscription has Azure Marketplace purchases enabled.

    Go to: Azure Portal > Cost Management + Billing > Your Subscription > Marketplace

    Make sure third-party purchases are not restricted by an Azure Policy at the subscription or management group level.

    Reference: Configure Marketplace permissions for Foundry Models

    3. Region support

    Confirm your Foundry project is in one of the two supported regions for Claude:

    • East US 2
    • Sweden Central

    Reference: Claude model region availability
