Outlook 2007 does allow export to a "Office Online" calendar. That works very nicely. There is even an iCal for the calendar. I tried to then add that calendar to Google Calendar, using it's iCal, but it did not work. Google Calendar would accept it at first, then a little while later would complain about not being able to open some URL.
So my wonderful utopia of having auto-sync of my work calendar to Google Calendar so that it was easily viewable by me or my wife is over for now. With Outlook 2007 I can subscribe to my own calendar, which works great. I can't subscribe to my wife's, probably because of security. At least I can see upcoming personal appointments on my Outlook calendar at work.
