It looks to me like you are really talking about Email Templates.
The Email Manager will need to select a Job Template linked to an Action Template that is set up to send emails.
The Action Template then needs to be linked to an Email Template which has been created with the system tag Incoming Email / IncomeEmail_Message or subject etc.
Unfortunaltey I dont have access to a functional install of Outlook so I cannot test this for you to make sure my logic is correct.
Let me know how you go!
