Outlook supports the use of CalDAV syncing via plugins(both free and non-free). You could use this to plug into a free caldav server like cosmo, or UW Calendar. The added benefit of using a caldav based service is that users would be able to also use different clients like Apple's iCal, Mozilla Sunbird, or Novell Groupwise to access the calendars. --Ray
