hello! I'm having issues with one of our users...we are running win2k3 exchange and majority of the users are using treo 650...the rest of the treo users are working fine, except for one of the users....ive setup his treo 650 to synchronize calendar, inbox, and sent folders....it works fine for a couple of days and then it will stop working....he's getting a "do u want to overwrite the calendar on your handheld with the one othe server"....we did a master reset on the treo 650 and even got a replacement device and the user still receives the error...

please help! thanks!
