A client would like a column in a list which essentially contains a number of email addresses for users and distribution lists within his corporate network. It would be something akin to the People Picker but that cannot be used as it does not surface distribution groups. What we actually need is to display the current user's Outlook Address Book (Global Address List) instead of the People Picker. Obviously they could manually enter email addresses for these people/groups but this would take much longer.
Any ideas?
