Azure AI Foundry Deployment Issue: Marketplace Subscription Cannot Be Completed — Region eastus

Hi @mpsim-2923

"This purchase cannot be completed" on Claude Opus 5.5 means the Azure Marketplace purchase check failed. Foundry never got as far as creating the deployment, so this isn't a region or quota problem yet.

Claude models in Foundry are sold by Anthropic through Azure Marketplace. When you click Deploy, Azure first creates a Marketplace subscription to the Claude offer for your Azure subscription. That step fails if either of these is true:

• your tenant restricts Marketplace purchases, for example with a Private Marketplace
• your subscription type isn't allowed to buy paid Marketplace offers

Get the real error code. The portal message is generic, and the inner error tells you which cause applies. In the Azure portal, open your resource group → Activity log, filter to Failed, and open the failed operation → JSON. ✔ To verify: you should see a code such as MarketplaceSubscriptionCannotBeCompleted or MarketplacePurchaseEligibilityFailed, plus a Correlation ID.

Check Private Marketplace. Ask your tenant Marketplace admin to check Azure Marketplace → Private Marketplace. If it's enabled, the admin needs to add the Anthropic Claude in Microsoft Foundry offer and its plan to the approved list. ✔ To verify: retry the Opus 5.5 deployment and confirm it gets past the purchase step.

Check your subscription type. In the portal, open Subscriptions → your subscription → Overview → Offer. Free Trial, credit-only, and some sponsored subscriptions can't buy paid Marketplace offers. Also confirm that a valid payment method exists, or that Marketplace purchases are enabled for your EA/MCA billing account. ✔ To verify: retry the deployment from a Pay-As-You-Go or Enterprise subscription.

Check for Azure Policy restrictions. Look for policies named "Foundry model deployments should only use approved models" or "…should meet eligibility requirements." These can block Anthropic models. ✔ To verify: on the Opus 5.5 model card, the Deploy button should show no policy-block reason.

If steps 2 to 4 all check out and it still fails, this is probably something only Microsoft can fix: other customers with this exact error needed their subscription allowlisted. That requires a support ticket.
