The Microsoft Outlook View Control is an ActiveX control that allows you to view Outlook e-mail folders on Web pages in Outlook 2000. The Outlook 2000 Update: E-mail Security protects you from attackers who attempt to exploit the vulnerability in the Outlook mail client. You can use the Outlook View Control on Web sites that are outside the Outlook mail client. This update prevents the control from being invoked by scripting or Hypertext Markup Language (HTML) code on a Web page potentially controlled by someone with malicious intent.

For more information on this issue, see the Microsoft Security MS01-038: Outlook View Control Exposes Unsafe Functionality. The Outlook 2000 SR-1 View Control Security Update requires that you first install Office 2000 Service Release 1 (SR-1) (which includes the original Office 2000 SR-1 update and the Office 2000/Windows 2000 Registry Repair Utility).
