I am running the registered version of Touchdown for Exchange on a Droid 2. It's been working well for the past few months, except for today, I noticed that it is not showing any emails in my inbox or other folders anymore. I am getting appointment alerts, but that is it. I checked my folders that are selected to sync and they are correct. I added a folder to sync to see if that would jar the application, but nothing. I haven't changed anything that I can think of. I rebooted the phone, still nothing. Anything I should be looking for here? TIA.
