Error 715-123420 when deploying model in Foundry

Hello @Prasad R

Error 715-123420 is different from the usual model quota, capacity, or deployment-configuration errors.

Several recent Foundry cases confirm that this error can occur when an account/subscription-level fraud or security signal blocks a model deployment, and the restriction requires review by the appropriate Microsoft backend team.

Since you're receiving the same error with both text-embedding-3-small and text-embedding-3-large, don't keep recreating resources, changing regions/SKUs, or repeatedly retrying the deployments. Similar cases have shown the same error across different models and resources because the request is rejected before normal model provisioning completes.

Your Basic support plan is the difficult part here because it normally doesn't provide Azure technical support cases. However, this error can't normally be resolved through a portal setting.

Since you've already opened this Microsoft Q&A thread, keep it focused on requesting help with the 715-123420 account/subscription restriction. Microsoft moderators have previously contacted affected users privately and collected the necessary information for investigation in cases involving this exact error.

Have the following information ready, but don't post sensitive subscription details publicly:

• Error code: 715-123420
• Subscription ID
• Tenant ID
• Foundry/Azure AI resource name
• Region
• Models affected
• UTC timestamp of a failed deployment
• Trace ID / Client Request ID / Service Request ID or correlation ID, if the portal provides them

Similar cases have required these identifiers so Microsoft can locate the failed deployment request on the service side.

If you have access to someone in your organization with an Azure support entitlement, they can alternatively open the technical case from the same tenant/subscription and reference error 715-123420.

Also, avoid creating another Azure account or subscription simply to work around the restriction. The appropriate resolution is to have the existing account/subscription reviewed.
