It's easy to find information on doing this the other way around (to switch), but unfortunatly the reverse problem does exist too... I'm in a situation where I need to take several iCal calendars with to dos, the address book, and mail in Apple Mail and put it all into Outlook 2003. Judging from the amount of information I've been able to find on this (approximately none) this doesn't seem like something people do often. Does anyone have any suggestions? I've tried exporting .ics files from iCal but they won't import in outlook.
