The Outlook Sweep feature is available in OWA and the Outlook Monarch client. The idea is that you clean up your mailbox by ‘sweeping’ unwanted items into somewhere like the Deleted Items folder. As it turns out, the Sweep feature uses both Inbox and Sweep rules to get its work done. Overall, Sweep is a pretty useful piece of functionality.
