Use Outlook Address Book to get POC data

[GeoMetry]

I have a hard enough time getting people to enter the required data. I hate to make them enter stuff that already exists in Outlook (and then keep it up to data in two places) I experimented with a link to the Outlook Global Address List but it seems slow and I guess I would need to code a form similar to the Address book. I would prefer to simply call the Outlook address book like I call a file dialog and get (or preferably link to) the contact information I need (Name and Phone)
