I found this great article by Rachel Wireman and how-to documentation on building Outlook integration functionality with C#, and it has downloadable source code.

She covers,

  1. General Outlook integration issues
  2. Creating an Outlook Contact with C#
  3. Programmatically sending emails to your Outlook contacts

It's short and the code samples are easy to follow and do on your own.
