I was having the same problem trying to get all of my Palm entries moved over.Intellisync, syncing with Outlook, and syncing with Yahoo all didn't work. Then I found Resync. It connects to either your palm, or your Palm Desktop and can sync with Outlook. Great program. It only took about 20 second to copy everything over, and it's free to try. I highly recommend it.
