I've been using Entourage (2004) for several years now, but I've gotten increasingly frustrated with how it syncs with iCal.
I seem to get a lot of duplicated events, for whatever reason. I'll delete the duplicates and think everything's OK, and then at some point down the road, I will once again have four or five copies of someone's birthday in the calendar.
So I'm thinking about just turning off the link between Entourage and Sync Services (at least for the calendars) and using iCal exclusively. I don't seem to have these syncing problems with contacts, FWIW.
I like using Entourage for my email but I like using iCal for reminders because it send me an email if I set it to. But now it always opens Mail when i have it send me a reminder! I dont want it to do that! Is there a way to make the calendar in Entourage send an email to, well, Entourage? Or make iCal send to entourage?
