Microsoft has released a new update for Exchange 2003 which restores functionality to Microsoft Exchange Outlook Web Access due to changes being made to Internet Explorer in the upcoming Microsoft Windows Vista Beta release.

In the upcoming Microsoft Windows Vista Beta 2 release, the Dynamic HTML Editing ActiveX control is being removed from the Internet Explorer browser. As a result, there is functionality missing that Microsoft Exchange Outlook Web Access relies on. This update replaces that deprecated functionality on the Microsoft Exchange servers so that Microsoft Exchange Outlook Web Access continues to function smoothly.
