Unregister a Custom Domain from a Storage Account in Windows Azure
Updated: February 13, 2014
Use the following procedure to unregister (delete) a custom domain from a Windows Azure storage account. After you unregister a custom domain from a storage account, customers can no longer access blobs in public containers by using the custom subdomain (format: http//<custom.sub.domain>/<mycontainer>/<myblob>). Customers can still access blobs by using the standard URI that Windows Azure assigns to blob containers: http://< mystorageaccount>.blob.core.windows.net/<mycontainer>/<myblob>. For more information, see Register a custom domain for your storage account.
To unregister a custom subdomain from a Windows Azure storage account
Sign in to the Windows Azure Management Portal.
In the navigation pane, click Storage.
On the Storage page, click the name of the storage account for which you want to unregister a custom domain.
On the storage account page, click Configure.
On the ribbon, click Manage Domain.
In the Manage Custom Domain dialog box, click Unregister.
