I try to share a calendar between a Mac and a PC over a WebDAV-Server. So I published an calendar file to a WebDAV-Server from the Mac. Subscribing the calendar on the PC (thanks to this plugin!) works fine, but Outlook won't publish the changes to the iCalendar file on the server. How could I sync with Outlook 2003 in both ways with an iCalendar over WebDAV?  Or is there a trick I don't see at the moment?

thanks in advance
