The Common Feed List (Common Feed List: A list of subscribed RSS Feeds that is saved with your Windows user profile. RSS clients, including Windows Internet Explorer and Outlook, use this list so that you do not have to configure subscriptions in each program.) is used by programs such as Outlook 2010 and Windows Internet Explorer as a way to share RSS Feeds information.
If you have configured Outlook to synchronize to the Common Feed List, you will see the same RSS Feeds in Internet Explorer and Outlook. If an RSS Feed is deleted from the Common Feeds List, it is also removed from Outlook 2010.
To turn on Common Feed List synchronization in Outlook 2010, see View the same RSS Feeds in Windows Internet Explorer and Outlook.
When Common Feed List synchronization is turned on, subscribing to RSS Feeds in Internet Explorer is the fastest way to add RSS Feeds in Outlook.
A list of all available RSS Feeds on the Web page is displayed.
The RSS Feed subscription is added to the Common Feed List.
Removing an RSS Feed from the Common Feed List also removes that RSS Feed from any program that is configured to synchronize with the Common Feed List, including Outlook.
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.
