But that's not the ID Barry meant. The Entourage database has its own set of
IDs for every object, including messages. The Message-ID in the source can
never, ever be re-written - it belongs to the source. But the database's
inner "tracking" of objects is re-written when you do a rebuild - it starts
over from scratch.
You can find the database's ID via AppleScript. Select the message in
question and then run this script:
tell application "Microsoft Entourage"
set theMsg to item 1 of (get current messages)
set msgID to ID of theMsg
end tell
--> 12345, or similar
If you omit the second line, the result will be something like:
--> incoming message id 12345
Although there are two subclasses 'incoming message' (i.e. received
messages) and 'outgoing message' (saved draft messages and sent messages)
they share the same ID-space. There only ever one message, whether incoming
or outgoing, that has a particular ID. When you rebuild, there ay be no
message with that ID or it's guaranteed to be a different message if there
is one that now owns that ID. But if you could track down the Message-ID
header in the source, you'd find the original message.
