 If you have the required access, but the delete request fails, it may be because there's a [lock on the resources or resource group](lock-resources.md). Even if you didn't manually lock a resource group, it may have been [automatically locked by a related service](lock-resources.md#managed-applications-and-locks). Or, the deletion can fail if the resources are connected to resources in other resource groups that aren't being deleted. For example, you can't delete a virtual network with subnets that are still in use by a virtual machine.
 
+## Accidental deletion
+
+If you accidentally delete a resource group or resource, in some situations it might be possible to recover it.
+
+Some resource types support *soft delete*. You might have to configure soft delete before you can use it. For more information about enabling soft delete, see the documentation for [Azure Key Vault](../../key-vault/general/soft-delete-overview.md), [Azure Backup](../../backup/backup-azure-delete-vault.md), and [Azure Storage](../../storage/blobs/soft-delete-container-overview.md). 
+
+You can also [open an Azure support case](../../azure-portal/supportability/how-to-create-azure-support-request.md). Provide as much detail as you can about the deleted resources, including their resource IDs, types, and resource names, and request that the support engineer check if the resources can be restored.
+
+> [!NOTE]
+> Recovery of deleted resources is not possible under all circumstances. A support engineer will investigate your scenario and advise you whether it's possible.
