I recently installed Exchange 2003 SP2 for enterprise edition. I've been trying to configure a windows mobile 5.0 hand held device to connect to the exchange server and take advantage of direct push email. When I enter the appropriate settings into the hand held device is says authentication fails - bad username or password. When I check the event viewer on the exchange server I can see where the logon failed. I'm not sure what's going on, I've tried every combination of settings for the device, but nothing seems to work -- please help.
