I'm not sure about your question, but the error message that you show indicates that you haven't added the assembly. To do this, expand your project, and right-click on References, and select 'Add Reference...'. Then go to the 'COM' tab (on VS2008 anyway) and locate "Microsoft Outlook 12.0 Object Library" (the specific version might be different on your machine depending on what version of Outlook is installed.) Highlight it and then click OK. I think that should clear your error, and will get you on the right path.
