Cannot Purchase a New App Service Domain

Cannot Purchase a New App Service Domain

Shreyash Naithani 0 Microsoft Employee

When I try to purchase a new App Service Domain, I receive the following error:

“The subscription Microsoft.Web.Hosting.Administration.Csm.Common.Domains.Models.SubscriptionModel is not eligible to create an App Service Domain.”

I previously owned the domain advancedatascience.com and have already deleted all associated resources, including the App Service Domain resource itself. However, this specific resource keeps reappearing automatically even after deletion.

The domain is not currently linked to any App Service or other Azure resource, but it still appears to be retained or recreated, blocking new domain creation.

In the resource group - I dont have any other resource -

My subscription is Visual Studio Enterprise subscription. And I know for this kind of subscription, have a limit of one app service domain.

Hey Shreyash, it looks like your Visual Studio Enterprise subscription is hitting its one-domain limit and the old advancedatascience.com registration is still “Active” in your subscription, even though you’ve tried to delete it. That’s why you keep seeing:

“The subscription … is not eligible to create an App Service Domain.”

Here’s what you can try to fully remove the old domain so you can buy a new one:

Remove any delete locks

In the portal, go to App Service Domains > advancedatascience.com > Locks, and delete any locks that are preventing removal.

Cancel or delete the purchase

- If you’re within the 5-day refund period, click **Cancel purchase** in the domain’s blade. - If you’re past five days, click **Delete** to remove it (you won’t get a refund but you’ll free up your one-domain slot). Wait for the operation to finish - Deletion/cancellation can take a few minutes. After it completes, refresh your portal view (or clear your browser cache) to make sure the domain is gone. (Optional) Use Azure CLI if the portal still shows it ```yaml az resource delete \

--ids /subscriptions/{your-subscription-id}/resourceGroups/{rg-name}/providers/Microsoft.Domain/DomainRegistration/advancedatascience.com ```

Verify your subscription quota - As per the docs, Visual Studio Enterprise only allows 1 App Service Domain. If you need more, you’ll have to convert to Pay-as-you-go.

Hope that helps! If you still run into the same error, let me know:

• Did you see any delete locks on the domain?

• Was the domain registered or deleted within the last 5 days?

• Have you removed the spending limit on your subscription?

• Are you using the portal or CLI when trying to delete?

Answer 1

The Visual Studio Enterprise subscription is limited to a single App Service domain. That limit applies as long as the subscription still has one App Service domain resource associated with it, even if the domain looks partially deleted or broken in the portal.

From the screenshots and error, the subscription still has advancedatascience.com as an active App Service domain resource, so the platform blocks creation of a new one. Deleting and seeing it “reappear” indicates a backend/domain‑resource inconsistency that can’t be fixed from the portal.

The only supported way forward is:

Keep using the existing App Service domain (advancedatascience.com) if it’s still needed, or
Have Azure Support correct the domain resource state or remove it on the backend so the subscription is no longer counted as having an App Service domain, or
Move to a pay‑per‑use subscription type that doesn’t have the one‑domain limit and purchase the new App Service domain there.

Because the domain object is stuck in an inconsistent state and the subscription is at its one‑domain limit, self‑service options in the portal won’t allow creation of another App Service domain.
