Question : In Sent Items, how can I tell if a message was sent with Read Receipt Requested

The "Message Options" toolbar item shows when I am creating a new message, but it does not show when I am reviewing and old message that I sent yesterday.

Sometimes it is important for me to know if the old message was sent with read receipt requested.

I know how to customize toolbars, but I could not find the "Message Options" under Toolbars  or under Commands

One..
open db in exclusive mode.
