**[TouchDown for OS X][1]**

> TouchDown® for Mac is the very first ActiveSync enabled desktop client for the Mac OS/X platform. It provides Mac Users with push email against ActiveSync enabled servers.

OS X mail app and all famous apps including Outlook 2011 for Mac don't support Active Exchange, but TouchDown adds Active Exchange to OS X. However, this app is paid.
