I am not sure what did not work for you: are you trying to set a header on
an outgoing message?


No. But I can't see/view an internet header on an outgoing message. I
click on the message, right click on it, select Options, and a dialog
box with the caption Message Options is presented. At the botton it has
a text box with the caption "Internet Headers" but it's blank. This
is the same in both O2003 and O2007. My O2003 goes thru a POP-3
account, the O2007 thru an Exchange server.

I was hoping I could get a link from an outgoing to an incoming message
where a link between the two apparent.

In my original post I mentioned one could but some sort of keyword in
the subject or body or both but the person could remove that info in a
response. I figured a header would be safe area to link the two messages.

Years ago I heard mail order companies, when hardcopy was used, would
put something like Dept 123 or J Smith on the envelope to identify a
mailing. I figured a header would be a viable way of doing so as well.
