Hi there,
I read your project and it is interesting and simple.I am an IT engineer and I work exclusive with VSTO project for Outlook, Excel, Word, etc.
In your case, I see that you want to execute this capture of contacts after "installation"; well I' not sure if you really wanted to say to execute it only one time, because an Outlook Extension is only installed once, so you will execute this routine once. Or if you wanted to say after "opening Outlook" to gather all contact information and store it on database. Anyways, in either case it is quite simple, I can even make it configurable so you set what type of database along with its credentials you want to use
I placed 3 days on my bid, 2 days to deliver your solution and 1 more just in case you need any modification or adjustment.
Well, I think that is all by now. If you have any question just send a message.
Regards,
Joe.
