Unable to Deploy Claude Opus 5.5 in Microsoft Foundry – "This Purchase Cannot Be Completed" Error

Hi Microsoft Community,

I'm experiencing an issue when attempting to deploy Claude Opus 5.5 through Microsoft Foundry.

Whenever I attempt to deploy the model, the deployment fails and I receive the following error message:

Error message:

"This purchase cannot be completed. Please contact Microsoft support via this link: https://go.microsoft.com/fwlink/?linkid=2101400&clcid=0x409"

Environment:

• Service: Microsoft Foundry

Model: Claude Opus 5.5

Deployment method: Microsoft Foundry Portal

• Azure Subscription Type: Pay-As-You-Go
• Foundry Resource Region: East US

Deployment Status: Failed

Troubleshooting performed:

Verified that my Azure subscription is active.

1. Confirmed billing/payment settings.
2. Confirmed Azure Marketplace purchases are enabled.
3. Tried deploying different models. But all failed.

Retried the deployment, but the same error persists.

Assistance Required:

I would appreciate some assistance in identifying the root cause of this issue.

In particular:

Is this error related to Azure Marketplace purchasing permissions, subscription eligibility, or an account-level restriction?

Are there any additional requirements or approval processes for deploying Anthropic models such as Claude Opus 5.5 through Microsoft Foundry?

Is there any action required from Microsoft to enable my Azure subscription to purchase and deploy Anthropic models?

If additional information is required, I would be happy to provide it.

Thank you for your assistance.
