Availability of Microsoft Office Document Open Confirmation Tool

Microsoft has released the Microsoft Office Document Open Confirmation Tool. This tool can be used to help protect you by always requiring confirmation before opening any of the following Microsoft Office document types in Internet Explorer and Outlook:

NOTE: Clip Art Gallery and PowerPoint Slide do not have associated file extensions.

• Microsoft Clip Art Gallery
• Microsoft Excel Worksheet (.xls)
• Microsoft Excel Web Query File (.iqy)
• Microsoft Excel OLE DB Query files (.rqy)
• Outlook Item Template (.oft)
• Outlook Item (.msg)
• vCalendar File (.vcs, Outlook client only)
• vvCard File (.vcf, Outlook client only)

• Microsoft PowerPoint Slide Show (.pps)
• Microsoft PowerPoint Template (.pot)
• Microsoft Word Template (.dot)
• Microsoft Word Backup Document (.wbk)
• Microsoft Word Document (.doc)
• Rich Text Format (.rtf)

NOTE: This tool is not the solution to the Excel 97 "ODBC Vulnerability" issue that can affect users of Microsoft Office 97; however, it can help to protect you by issuing a security warning, allowing you to choose not to open a document. The Confirm tool changes the trust setting for Office document types originally altered by Office Setup. See the MORE INFORMATION section for information about how to manually configure the "Confirm open after download" setting for any file type.

This tool is available at the following Microsoft Web site: Internet Explorer and Outlook issue a security warning by default before starting unknown programs or opening unknown files so you can choose whether or not to open them. This tool gives you the option to treat Office documents in the same way, preventing them from automatically opening when you click a link to an Office document, browse to a Web page that hosts an Office document, open e-mail that has an Office document, and so on.
