Lifecycle Services tried to deploy the environment, but your Azure subscription doesn't support additional storage accounts. Determine if there are any existing storage accounts that you can delete. If not, you'll need to create a support ticket with the Azure support team. When creating the support ticket, be sure to indicate that the ticket is for billing support. After you have increased the number of storage accounts that your subscription can support, please try to deploy the environment again.
