Policy
Override published sync interval
This policy setting allows you to ignore the synchronization interval specified by the RSS publisher. By default, Outlook follows the synchronization interval specified by the RSS publisher and RSS Feeds will not be synchronized more often than allowed by the RSS publisher. If Outlook does not follow the RSS publisher's synchronization interval, the RSS publisher may suspend Outlook from synchronizing the RSS Feed. If you enable this policy setting, Outlook will always ignore the synchronization interval specified by the RSS publisher. If you disable or do not configure this policy setting, Outlook will always follow the synchronization interval specified by the RSS publisher.
