I have never put much thought into the Housekeeping categories in VM Pro until now that a customer has asked about messages being deleted. I have searched through everything I have and can't find anything that describes when a message would be marked as saved or old. I am running all of my systems in Intuity mode so maybe it is in there for IP Office mode or something. There is no save option when listening to a message. How does it know whether the message is marked as saved or old?
