My email account at school was switched from FirstClass to an Exchange server just over a week ago, while I was in Europe. Since returning home, I've been getting to know the Microsoft programs designed to take advantage of Exchange--Entourage (on the Mac) and Outlook (on the PC)--a bit better. In particular, I've been able to load my contacts, my calendar, and my "to do" list, with mixed results. It's frustrating that the categories don't sync from machine to machine. Add to that the different feature sets in Entourage (with its attractive Project Center) and Exchange (which handles shared calendars, among other things, differently) and the yet-to-be-resolved syncing issues with my Palm PDA, .Mac, iCal, and Apple's Address Book and Mail, and and it looks as though I will be experimenting for a while until I have a PIM system that works well for me.
