Would like a status or properties window or tab that could be turned off and on by policy that allows users to easily find out out what the status is of their sent email and appointments.
The status for each recipent would show delivered or opened for mail and would show delivered, accepted, or declined for appointments.
For external people, the could simply receive back a successfully transferred status if the message didn't get returned.
Example of sent email status to an email that was sent to 2 internal people and 1 external person

On a side note, my company is migrating to Domino 8.5 first quarter of 2009. The current email system has this functionality and is very popular among the users. I have attached screenshots of what these screens look like.
