You have selected the wrong tab in the link manager. Select this tab: 
Then find the Microsoft.Office.Interop.Outlook library. If you have several options, then look at File Version info - there is an Office version that you can work with: 12. * - 2007, 14. * - 2010, 15. * - 2012.
The best choice is 14. *, but others will work mostly.
I also need to worry that Microsoft suggests not using server side interop ( link )
