Here is a list of a few that I found: 1. I have several folders in my Exchange mailbox. All of them show up on my Droid but they show up as empty. Hitting 'Refresh' does not fix this. Not being able to sync my Exchange folders may be a showstopper :icon_evil: 2. My corporate Exchange server has a Global address book that shows up on my iPhone but does not show up on my Droid.
