Using Outlook to subscribe to an RSS Feed is quick and easy and does not involve a registration process or fee.
After you subscribe to an RSS Feed, headlines will appear in your RSS folders. RSS items appear similar to mail messages. When you see a headline that interests you, just click or open the item.
To add an RSS feed to Outlook, copy the LINK for the RSS feed as usual, then go into Outlook, right-click on the "RSS Feeds" folder below your InBox, choose "Add a new RSS feed," and paste the link there.
