Exchange/Outlook2003 enable Timezone to always be on

So got a question this morning from my boss. We run Exchange 2003 and Outlook 2003. He would like to have the Calander so that the timezone setting is always shown and you do not have to click the Timezone button each time you do a calander appoitnment. I can’t find anywhere to turn this setting on for an entire exchange server.

My first reaction after having gone thru this is.. no.. but I hate that as a simple answer. Anyone have a differnt answer?
