Studying the Google Calendar again, I did found a way to import Outlook meeting data into it, from a tip from a Google Calendar Help forum. It seems you need to change your Windows XP system language into US English before doing the Outlook data export, to get date format right for Google Calendar. Well, there still seems to be various kinds of bugs in it, but the idea of having an easy way to share calendars is of course nice. Now, if this would only really work… 😦
