This article describes update 3191923 for Microsoft Office 2016 that was released on September 5, 2017. This update has a prerequisite.

Be aware that the update in the Microsoft Download Center applies to the Microsoft Installer (.msi)-based edition of Office 2016. It doesn't apply to the Office 2016 Click-to-Run editions, such as Microsoft Office 365 Home. (How to determine?)

Improvements and fixes

  • This update enables certain special characters for the Add-in commands in the Office 2016 ribbon.

  • This update improves the Internet Explorer session to make sure that you can reuse the Internet Explorer process for applications in Outlook Inspector window.

  • This update fixes some high DPI issues for add-ins. For example, you have a high-resolution monitor and a lower-resolution monitor. When you start the host on the high DPI monitor, start a task pane add-in, and then drag the window over to the lower DPI monitor. The add-in will be resized to a much smaller version that’s not usable.
