Azure OpenAI: Deployment Failures Due to Unusual Activity Error

Azure OpenAI: Deployment Failures Due to Unusual Activity Error

Bakir-3311 0

Problem description

I am experiencing repeated failures when attempting to create new model deployments in Azure OpenAI in the Sweden Central region. The error code received is 715-123420, with the message stating that the request has been detected as unusual activity for my account. This issue began after submitting several deployment requests in quick succession while migrating workloads to EU data residency.

Environment

Service: Azure OpenAI; Resource type: Azure AI Foundry; Region: Sweden Central.

What I've already tried

I created multiple Azure OpenAI resources in Sweden Central as part of the migration. On November 5th, I submitted several deployment requests in rapid succession. After the failures started, I retried deployments, but every attempt on the affected subscription resulted in the same error. I also performed capacity updates on existing deployments, which succeeded, indicating that the issue is specific to creating new deployments.

Current status

Currently, all new deployment attempts are failing with error 715-123420. I am seeking guidance on how to resolve this issue and whether the block on creating new deployments can be lifted for my subscription.

Hi @Bakir-3311

Error 715-123420 isn’t documented in Microsoft’s public Azure OpenAI error reference, so there is no verified customer-side command or configuration change that can remove this restriction.

The error text explicitly requests contacting Microsoft Support. Since existing deployments can still be updated while all new deployment creations fail across the affected subscription, this doesn’t match the normally documented quota, capacity, authentication, or request-payload errors. However, only Microsoft can confirm whether an account or subscription protection control caused the block.

Recommended actions:

Check Azure Service Health for an active Azure OpenAI or Microsoft Foundry incident affecting Sweden Central. Service Health displays subscription-specific service issues and affected regions.
Open Subscription → Activity log, locate the failed Microsoft.CognitiveServices/accounts/deployments/write operation, and record its correlation ID. Azure documents the correlation ID as the identifier Support uses to trace failed control-plane operations.
Create an Azure support request from Help + support → Create a support request, or from the affected resource under Support + Troubleshooting. The account needs Owner, Contributor, Support Request Contributor, or equivalent Microsoft.Support/* permission at subscription scope.

Include:

Error code 715-123420 and complete error message
Subscription and tenant IDs
Affected resource IDs and Sweden Central region
Failed model names, versions, and deployment types
UTC timestamps
Activity Log correlation IDs
Trace, client-request, or service-request IDs shown by the portal or API
Confirmation that existing deployment updates succeed but new deployment creation fails
A request for review of the unusual-activity restriction

Do not publish subscription IDs or diagnostic identifiers in the public Q&A thread; provide them only through the private support request.

Microsoft Support must inspect the subscription-side enforcement state and determine whether it can clear the restriction.
