Simple feature request that will never happen: All Internet emails have a GUID field, and all users who have a copy of a unique message have that one GUID for it.
Why can't there by an "email:$MessageId" URI scheme and why can't Outlook handle these URIs with 1) open that message if I have it; or 2) "You did not receive that message."
I've looked into part of this before. Outlook has message URLs, specific to YOUR database, and they break if you move a message to another folder. Useless.

And someone has already thought of this:

@everlastingrocks Cool. Just needs functions to get URIs out of message view forms in Thunderbird and respond to URIs from the shell command line parameters.
