You can't, at least not with Apple's Mail program, which requires Exchange 2007 or later. Likewise, Microsoft does not support Exchange 2003 in Outlook 2011 for OS X; however, you can use some workarounds to implement some support for the service, such as that outlined here: http://guycoen.wordpress.com/2010/12/09/outlook-2011-on-mac-and-exchange-2003/

Your iPad uses ActiveSync to connect to Exchange. ActiveSync supports Exchange 2003.
Lion and Mountain Lion use Exchange Web Services to connect to Exchange, This requires Exchange 2007 SP2 UR6 or later.
So that's a long way of saying "you can't."

The only way I've found to solve the same problem is to use Microsoft Entourage. This is a part of Microsoft Office 2008. This looks completely bad, but it works with Exchange 2003 accounts somehow.
