I got the upgrade to 2.2 earlier this week on my Moto Droid. I haven't been able to get my email or calender working since. My IT guy at work does not have a solution for me. It is not an issue with the corporate server. My phone just shows an error that says it cannot connect to the exchange server for the email and calender functions. I turned the phone off and restarted a couple times, didn't work. I tried removing and re-installing my exchange account (bad idea). VZ Wireless had no answer. Motorola had a wait time of 2-3 hours for their technical support. Please help. I have been using the Touchdown app for a temporary fix. Please help! I do not want to have to sit on the Motorola tech line for 2 hours.
