I have been charged with writing an Outlook add-in that would check
and possibly change certain messages upon receiving and sending
emails. I pretty familiar with Map, but don't know a lot about
programmable support for outlook itself. So, my questions a

1. Is this possible? (check and change messages upon receiving and
sending)

2. What would be the best way to go about it? I'm a bit overwhelmed by
the options out there... There are VBA/Ole/COM-ish type of things,
Outlook Extension APIs, Outlook Api, Mapi Api, VS Shared addin, VSTO
type of project? I imagine some of these are different orientations on
essentially the objects, but I would like to not go down the wrong
path.

3. Since prefer a c# approach, (c++ is also nice) I'm thinking of a
VSTO addin. Any problems with this?

4. How do i get a hold of messages as they come in?

Thanks in advance,

J
