This security update resolves vulnerabilities in Microsoft Office that could allow remote code execution if a user opens a specially crafted Office file. To learn more about these vulnerabilities, see Microsoft Security Bulletin MS16-107.

Note To apply this security update, you must have the release version of Excel 2016 installed on the computer.

For a complete list of affected versions of Microsoft Office software, see Microsoft Knowledge Base article KB3185852.

Improvements and fixes

This security update contains improvements and fixes for the following nonsecurity issues:
  • Add some new and improved data connectivity and transformation features. For more information, see KB3118296.
  • The Workbook.SendMail method doesn't work correctly to send a workbook through an email message in Excel 2016.
  • Accessibility applications such as screen readers can't recognize new content in cells in Excel 2016.
  • If you have multiple workbooks open concurrently in Excel 2016, and Auto-Recover is triggered on one of the workbooks, some of other workbooks that don't have any data models are corrupted.
  • Assume that an Excel worksheet object is embedded in another Office 2016 application, and the worksheet contains an ActiveX control. When you active and deactivate the Excel object in the Office 2016 application, Excel 2016 crashes and you receive the following error message: 
    The server application, source file or item cannot be found, or returned an unknown error. You may need to reinstall the server application.
  • The Sheets.Select (False) method doesn't work after you install MS16-088: Description of the security update for Excel 2016: July 12, 2016.
