Yup, the same page where you set up your connection for iCal: http://www.toodledo.com/connect_ical.php
You want the "All Others" link for Outlook. It is a bit confusing because in addition to being a program on Macs, iCal is a general name for a file type. So you will just set up an iCal subscription in Outlookk:)
Unlike the sync tool, the calendar link will only be one way though.
