I need to create a special button in Outlook 2007. When clicked it
should rewrite the subject header of the email being composed, and
then send the email. Which way should I be headed?

I was looking into VSTO for a while, but someone said it's still a
little unstable and I can't seem to find many books on it anyway.
Every book on Outlook programming in my local Borders talks
exclusively about VBA and doesn't even *mention* VSTO. So maybe I
should go with VBA?

Would this be a macro thing? Create a macro written in VBA? I think
I read somewhere that you can make a button that activates a macro.

Where's my square one?
