Storage Account: Issue with Recovery — Account Already Taken Error

Likely cause: this restore path can fail with StorageAccountAlreadyTaken when the name is no longer available globally, or when backend recovery preconditions are no longer satisfiable. For deleted storage accounts, recovery is best-effort and not guaranteed.

From Microsoft docs, recovery works only if all required conditions are true:

1. Deleted within the last 14 days.
2. ARM-based storage account.
3. No new storage account with the same name was created after deletion.
4. Resource group exists.
5. Caller has RBAC permission Microsoft.Storage/storageAccounts/write.

Suggested checks (in order):

1. In portal Restore deleted account, confirm the account appears under the same subscription and select it from the restore list.
2. Verify name availability globally:
   • az storage account check-name --name <accountName>
   • If unavailable and you cannot find it in your subscriptions, the name is already in use in another subscription/tenant.
3. Confirm RBAC on the restore operator (for example Contributor/Storage Account Contributor scope that includes write).
4. If CMK was used, ensure Key Vault/key are restored before account restore.
5. If all prerequisites are met and restore still fails, open Azure Support and provide:
   • Storage account name
   • Subscription ID
   • Deletion timestamp (UTC)
   • Correlation ID / Activity Log operation ID from failed restore

Important limitations:

• If the name has been reused externally, the original account generally can’t be recovered under that same name.
• Private endpoints are removed on delete and aren’t recreated automatically after recovery.

Hi Anuruddhi,

You've already checked most of the usual causes here.

Microsoft does state that a deleted storage account can be eligible for recovery when it was deleted within the last 14 days, used the Azure Resource Manager deployment model, the original resource group exists, and a new storage account with the same name hasn't been created. You also need an Azure Role Based Access Control (RBAC) role containing the Microsoft.Storage/storageAccounts/write permission. Here is a link I've attached with details >>

As your account still appears in the deleted account recovery list but the restore itself fails with StorageAccountAlreadyTaken, I wouldn't recommend creating another account with that name or making further changes while recovery is being investigated.

I recommend raising an Azure Storage support request and provide:

• The deleted storage account name
• Subscription ID and resource group
• Deletion date/time
• The StorageAccountAlreadyTaken error
• Details/screenshots showing that the account is still offered for recovery

Microsoft notes that storage account recovery is a best-effort operation and isn't guaranteed, even when the recovery conditions are met.

You can create a support request from Azure portal → Help + support → Create a support request.

From here the best team will be able to assist further. I hope this helps.
