Sorry, I know nothing about writing a MAPI store provider. What the OP wants
cannot be done using a COM addin, as Sue mentioned. It can only be done
using a custom store provider.

You really want to be talking with Ken Slovak, who has several books about
all this. Go rummage on his web site, and see if he has a forum there,
through which you can make contact. He might not see this thread here for
a
while. Below is his signature plate from a recent message:
