Disabling Email Order Notifications to Administrator

To disable email order notifications to the administrator, but send them to customers:

1. In the administration panel, go to Orders > 'Order statuses.
2. On the opened page, click on the necessary order status (or on the edit link in the same line) to open the Editing order status page of this status.
3. Disable the Notify orders department option.
4. Click the Save button to apply the changes.

After that, no email notifications of the changed order status will be sent to the administrator.
