Hi fellows,
I want to customize the dialog box that appears when you double click
any entry in the address box dialog in outlook 2007. I searched the
web with many saerch keys but no luck.

The dialog box seems to show the properties of an ExchangeUser object.

If anyone has Windows Live Messenger installed he will find the
Actions button customized with 2 new items in the drop down action
list.

I think VSTO is the best way to go but I do not know where to start

Appreciate any hints

Thanks
