Have you actually gone to your references and added a  NET reference to the  Microsoft Office Core  library   If you downloaded the example application  the answer would be yes   If that is the case  follow the advice in the article      If your system does not have Microsoft Office Outlook 2003 you may have to change the References used by the  OutlookConnector  project  That is to say  if you received a build error described as  The type of namespace name  Outlook  could not be found   you probably don t have Office 2003  Simply expand the project references  remove the afflicted items  and add the COM Library appropriate for your system  If someone has a dynamic way to handle this  I d be curious to see you ve done    That should solve your problem   If not  let us know
