View the same RSS Feeds in Windows Internet Explorer and Outlook
When you use Windows Internet Explorer 7 or later and Microsoft Outlook 2010, you can view and maintain the same RSS Feeds subscriptions list in either program. You do so by sharing one RSS Feeds subscription list via the Common Feed List in Microsoft Windows.
The Common Feed List is used by programs such as Outlook 2010 and Internet Explorer as a common location for RSS Feeds information. When you add an RSS Feed to any program that uses the Common Feed List, that RSS Feed is available in all programs automatically. If an RSS Feed is deleted from the Common Feed List, it will also be removed from Outlook 2010.
Note Deleting an RSS Feed in Outlook 2010 does not remove the RSS Feed from the Common Feed List or other programs using the Common Feed List.
The first time you add an RSS Feed to Outlook 2010, you are prompted to choose whether or not you want to keep your RSS Feeds subscriptions list synchronized between Outlook and the Common Feed List. Regardless of the option you choose, you can change your choice later.
Click the File tab.
Under RSS Feeds, select or clear the Synchronize RSS Feeds to the Common Feed List (CFL) in Windows check box.
