I have been using Entourage for two years. But it has gotten bloated and slow. I decided to start using iCal, iAddress and Mail exclusively. And I'm generally happy with the change and the increase in speed. Mail and iAddress did fine in the transition. But iCal seems to need Entourage and keeps giving me multiple calendars many but not all duplicating existing calendar entries. Early on in the switch over I went to Entourage preferences and turned off the sync for the apple software. My iPhone also seems to rely only on Entourage for data and I get double entries for each calendar event. When I go to my list of calendars which are all Entourage, I uncheck one and some entries disappear. Right now I have about 15 Entourage calendar versions. The problem seemed to get worse last month when I finally upgraded from Leopard to Snow Leopard. Help. Entourage is haunting me.
