Azure AI Foundry deployment blocked by error 715-123420 – Basic support plan

Frolík Dominik 0

Hello,

we are unable to create a new model deployment in Azure AI Foundry.

The deployment fails immediately with the following message:

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

The affected model is: gpt-5.6-terra

Error type: BatchARMResponseError

Client request ID: 79304e01-0228-43c0-aa91-0d113c9b1792

Trace ID: 28b91c34-e16b-4b6b-ba22-e7ce1f5b60b2

Service request ID: 3f9e92c1-6f1b-4fcc-b4a1-d9d0f71b85fd

The deployment fails before provisioning is completed.

Our Azure subscription is active, but we only have the Basic support plan, so we cannot create a technical support request through the Azure portal.

Could a Microsoft moderator please determine whether this is a false-positive account-level or subscription-level restriction?

Could a Microsoft FTE moderator please contact me privately or open a secure collaboration request with the appropriate Azure AI Foundry / Azure OpenAI backend, fraud protection, security, or trust and safety team?

I can provide the full Subscription ID, Tenant ID, Resource ID, region, deployment timestamp and any additional information privately.

Region: WestEurope Deployment type: Data Zone Standard UTC timestamp of failed deployment: 20.7.2026 8:40

Thank you.

Hello Frolík Dominik,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

I understand that your Azure AI Foundry deployment blocked by error 715-123420 – Basic support plan.

This is not just a minor system block, Your deployment is blocked by Microsoft-side account/subscription/service protection. Region, quota, and model availability should be checked once, but they are not the real fix because the error says unusual activity and fails before provisioning. Also, there is no safe public workaround and no community-only solution that can clear this. The fix requires Microsoft backend action through an authenticated private support case. If you don't have Azure paid support, contact Priority Customer Support -PCS.

I hope this is helpful. Please! Do not hesitate to let me know if you have any other questions, steps or clarifications.

Please do not close the thread by upvoting and accepting the answer if any part of it is helpful.

Thank you for confirming that this requires Microsoft backend action.

I have only the Azure Basic support plan, and Azure Portal does not allow me

to create a technical support request.

Could you please escalate this case through Priority Community Support and

create a private authenticated support case on my behalf?

Please send me a private message so I can securely provide the Subscription ID,

Tenant ID, Resource ID and any other required details.

The relevant diagnostic identifiers are already included in the question:

Client request ID

Trace ID

Service request ID

The deployment remains blocked by error 715-123420.

Thank you.

Thank you. I have already posted this technical issue on Microsoft Q&A using the appropriate Azure service tag.

According to the Priority Community Support documentation, complex issues that cannot be resolved through Q&A should be escalated by a Microsoft engineer by creating a support ticket on the customer's behalf.

Error 715-123420 requires Microsoft backend action and cannot be resolved publicly.

Could you please escalate this case and contact me privately so I can provide the Subscription ID, Tenant ID, Resource ID, exact UTC timestamp, and any other required information securely?

Thank you.
