I knew I forgot to post something! Although I don't have much first-hand experience with PIMs, I do remember reading something of Lotus' offerings, and how they work out well for most people.
I just took a look at IBM's website, and what you're looking for is "Lotus Organizer." I suggest looking in that direction.
Click.It's 60 bucks, by the way, so make sure it has all the features you need.
