Outlook Mobile Access and Exchange Server ActiveSync features, formerly found in Microsoft Mobile Information Server 2002, are now built-in with all Exchange Server 2003 Standard installations.

Complementing the Outlook 2003 and Outlook Web Access mobile improvements, Outlook Mobile Access and Exchange Server ActiveSync help enable secure corporate e-mail on a range of mobile devices including browser-based mobile phones, Microsoft Windows Powered Pocket PC, and Microsoft Windows Powered Smartphone devices.

Adding this functionality to the core Exchange Server 2003 product reduces the need to deploy additional mobile server products in the corporate environment, thus lowering the total cost of ownership.
