Implementing Check Names and Browse for Email Addresses

Implementing Check Names and Browse for Email Addresses

  
Hi!

We are using Service Studio version 6.0.   My .net application has a screen for sending emails.  I would like to implement a checkname/browse for names feature.   (Similar to what Micro Soft has for Outlook, SharePoint and other office applications)  SEE BELOW

Has anyone built a component to do this in their applications?  Essentially, I'm looking to allow the user to enter a user name or email address and have the application validate the email address against our exchange server, or Active Directory.
