outlook add-on

I need to build an addon to Outlook 2003 so that the following happens. Go to Public Folders/Shared Contacts. Right Click a Contact Now we see some extra options. New Letter to Contact New Fax to Contact Click New Letter and the contacts details are merged into a Word Template (the same for the Fax). This should be acheived without having Outlook complaining about security - have a look at this for example - [login to view URL]
