I contacted Tripit tech support and they claim that adding the feed to iCal and then turning on Outlook Sync Services will do the trick. I have tried it several times and it does not work. The process seems fairly straight forward - the only part that has any user input is the Sync Services. I was hoping that the person that got this working could weigh in and let us know how he configured this.

Under Sync Services when I select Calendar on the left I see two accounts to sync with: "On My Computer" and "Exchange". I have selected both. Then beneath that I have a dropdown box "Outlook folder to add new items to" and it has two options "On My Computer / Calendar" and "Exchange / Calendar". The dropdown box appears like it can be set for each option in the window but in fact can only be set one way or the other for all items (poor interface design!). I have tried setting it both ways and it makes no difference.

Bottom line - I get Outlook items synchronized with iCal. But the calendar feed never shows up in Outlook in any calendar.

Anyone got this working?
