Microsoft Outlook by default uses the RSS feeds from your IE7 or IE8 common feed list.

If you don’t use Outlook as an RSS reader, then there is really no reason to have that feature enabled and wasting space in your mailbox.

Note: If you aren’t using Internet Explorer or Outlook as a feed reader, you could simply delete all of the RSS feeds.

Disable Outlook Common Feed RSS Sync

To turn this off, go to Tools – Options from the menu.

Click the Advanced Options button on the Other tab.

Now you can uncheck the item “Sync RSS Feeds to the Common Feed List”.

Now that you’ve disabled the Sync feature, you can delete all of the feeds from under the RSS Feeds folder.
