title: How to synchronize iCalendar with Outlook
body: <p>I store my .ics calender on a webdav server. With Thunderbird/Lighning I can read <em>and</em> write the calendar. But how to deal with Outlook?</p>
  
  <p>Outlook can only read the ics file remotely. Synchronization using google calender is not an option for me.</p>
