I'm soure that outlook has progressed since I used it last!

What I'd like to do is automatically (that is from a script/command
line/program) send an e-mail to somebody using outlook that has the
voting buttons set. When they reply, I'd like to process the reply
automatically and use their result.

For example: If I send an e-mail with 'yes' or 'no' in the voting
buttons and 'Do you approve this change?', then, when the reply comes
back, I'd like to be turn that into a boolean that I can use to change
the status of my object to 'approved' or 'not approved'.

I need this to interfact to an API of a fairly old program...

I've looked at things like 'outlook.exe /c ipm.mail' but these all seem
to bring up some sort of gui - maybe I haven't found the right
documentation of the outlook command line - if so, please point me in
the direction of this, and I'll be happy!
