If that is Access code, I fail to see how it approaches what you asked about, which was how to control the email process on someone else's pc. That is, I click the link in the email I accepted and opened, and you want to control certain properties (e.g. CC or subject) and the body content (possible to a degree) BUT you also want it to automatically go to you without user intervention. The last part is what I'm saying surely cannot be possible. The rest, OK. Have I misunderstood the goal/question/problem?
The more we hear silence, the more we begin to think about our value in this universe.
