Hi

I need to develop an add-in for outlook 2003 and above that does the
following;

When a certain external application sends email via outlook, the outlook
add-in adds certain info into a database table. Some of this info comes
from the calling external application.

I have not developed an outlook add-in before but I am a proficient
developer of vba and vb.net. What would be a good place to start for this
sort of project?

Many Thanks

Regards
