I use Entourage as my main calendar. I sync Entourage to iCal and from there to my iPod Touch. I don't use any categories in Entourage but iCal seems to grow with new Entourage calendars - there are six now - why I don't know. When everything syncs to my iPod through MobileMe, I end up with duplicate entries. For example, there are six entries for President's Day (each with a different colored button to the left of the entry. I've tried to uncheck (and then delete) all but one of the Entourage calendars in iCal, but they keep coming back. I'm sure that this is a simple problem but I can't figure out how to stop it. Can I sync Entourage and my iPod without using iCal? Can anyone help? Thanks.
