Executive Summary:

Microsoft Office Outlook 2003 does not provide native Really Simple Syndication (RSS) feed functionality, although some third-party options are available for incorporating RSS. Microsoft Office Outlook 2007 provides the ability to consume RSS feeds natively. However, third-party solutions that integrate with Outlook 2007 and Outlook 2003 provide better scalability and easier administration.

If you use different versions of Outlook to access the same profile, you need to be aware of Outlook version compatibility problems that can corrupt your rules. You can use Outlook Web Access (OWA) or Outlook switches to delete and recreate corrupt rules.
