Azure AI Foundry deployments fail with error 715-123420: “Our system has detected this request as unusual activity for your account”

Question

I’m trying to deploy AI models in Azure AI Foundry using a subscription with free AI founders credits. Model deployments that worked previously are now failing immediately for all models.

Based on other posts, this appears to be a platform-level fraud/risk hold (RTFP) on the subscription rather than a configuration issue.

Hello @James Barrett

Yes, your assessment matches other reports of 715-123420.

Microsoft moderators have confirmed in recent Q&A cases that error 715-123420 (or 555420) indicates that Azure AI Foundry has blocked the model deployment because of a fraud/risk signal, and the request requires review by the appropriate Microsoft internal team.

Since deployments that previously worked are now failing immediately across multiple models, this is unlikely to be a normal model quota, capacity, RBAC, or deployment configuration issue.

I would recommend not repeatedly retrying deployments or recreating Foundry resources, as those actions won't clear a platform-level restriction.

Next, request a Microsoft review. Provide the following information privately to Microsoft Support or a Microsoft Q&A moderator:

• Error code: 715-123420
• Subscription ID
• Foundry/Cognitive Services resource ID
• Model and deployment SKU attempted
• Region
• UTC timestamp of a failed deployment
• Trace ID, Client Request ID, and Service Request ID, if available

Since you're using a subscription with free AI Founders credits, also mention that in the case so Microsoft can verify the subscription's eligibility/status as part of the review.

Do not post the subscription ID or other sensitive account information publicly.

A Microsoft moderator should be able to request these details through a private message and route the case to the appropriate internal team.
