I am on the cusp of returning my Nokia N900. I have tried setting up Mail for exchange to sync with my work 2007 exchange server with no luck. I use the same settings that have been successful on my E series phones and iPhone. I get to the first sync page and when sync is started the progress box fills up to one fifth and then stops. No error messages. My IT guys are stumped. Anyone with suggestions? I am using T mobile Internet with a plan that works on my other devices.
