Hello Microsoft Q&A Team,
I am using an Azure for Students subscription to conduct hands-on experiments with the official Microsoft Learning AI-300 GenAIOps labs.
Issue: Azure AI Foundry deployment blocked by error 715-123420
On October 23, 2026, I encountered the following error when running azd up:
InvalidTemplateDeployment
Microsoft.CognitiveServices/accounts (2025-06-01)
reported preflight validation errors.
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.
Environment:
- Subscription: Azure for Students
Region: Japan East
Resource group: rg-lab4
Tool: Azure Developer CLI (azd)
Repository: https://github.com/MicrosoftLearning/mslearn-genaiops
Background:
I previously deployed the Azure AI Foundry resources successfully.
I have been creating and deleting lab resources while testing deployment procedures for educational purposes.
I also encountered an earlier, unrelated RequestConflict issue involving Bicep resource dependencies, which I successfully resolved.
However, when attempting to deploy the environment again, Azure rejected the new deployment during preflight validation with error 715-123420.
All activities were performed for legitimate educational experimentation. I suspect this might be a false-positive automated risk restriction, but I cannot confirm the cause.
Unable to create an Azure Support Request:
I attempted to create a support request through the Azure Portal.
However, clicking "Create a support request" only opened the "Support + troubleshooting" panel. Entering a problem description and clicking "Go" did not proceed to the support request form.
I also tried Microsoft Edge InPrivate mode, but encountered the same behavior.
As I am using Azure for Students, I understand that free technical support may be limited.
Request for Microsoft Moderators:
Could a Microsoft moderator please help me with the following?
Check whether my Azure account or subscription has been restricted by an automated risk or fraud-prevention system.
Help escalate this issue to the appropriate internal Azure Foundry or risk/security team for review.
Initiate a private message if subscription details, tracking IDs, or additional diagnostic information are required.
Advise whether any further verification is necessary to restore normal Azure AI Foundry deployment capabilities.
I can provide my subscription ID, deployment tracking ID, screenshots, and other requested information privately.
I would greatly appreciate your assistance in reviewing this possible false-positive restriction so I can continue my AI-300 educational labs.
Thank you very much for your help.
