3816307 - How can I disable Workflow Email notifications?

There are five email notifications that can be set under Workflow configuration:

• Expiration Email To Approver: This notification is sent if the workflow is configured to send the report to another approver when the approval time expires. The original approver receives this email.
• Approval Request Notification: This notification is sent to the approver when the report/advance is submitted by the employee.
• Status Change Notification: This notification is sent to the submitter when the workflow status of the report/advance changes.
• Sent Back Notification: This notification is sent to the submitter when the report/ advance is sent back to them. If the report was submitted by a delegate, that delegate also receives this notification. NOTE: This notification is always sent; it is not configurable based on the user Profile preferences.
• Courtesy Email Notification (expense reports only): This notification is sent to a user's default approver if that person is not the first approver in the workflow or if another approver was selected by the user for the first step in the workflow (if the company allows users to select approvers).
