The installation of Outlook Social Connector is different from most downloads. Besides downloading OCS (for Outlook 2007 and Outlook 2003; included in Outlook 2010), you must download provider files for each social network you want to connect to. Note: To use Facebook in OCS, you must allow a 3rd-party app (which's default setting). If you've edited these settings in Facebook, you may need to edit them again. On your Facebook home page, click Account, and then click Application Settings.
