I believe two forms of Outlook integration would be appropriate (and consistent with the features already found in competing products)...
First, get rid of that silly 200-contact limit and allow Outlook contacts to be searched & selected directly from within Street Atlas (without any import/export). Bonus points will be provided for filtering by Outlook categories and using either a home or work address from Outlook.
Second, implement functionality similar to the "Display Map of Address" button that already exists within the standard Outlook toolbar for launching a browser with a URL for MapPoint to display. Instead of using a browser and MapPoint, use Street Atlas for the display.
