Over the next few weeks, check for reports about problematic issues, and if all seems well, apply the update.

What IT needs to know: Because this is a security update, it should be applied relatively soon. For details, see Release notes for Microsoft Office security updates. It also fixes a number of security holes. This build fixes two bugs, one that causes Access to close unexpectedly when exporting from an SAS application to a Microsoft Office format, and another in Outlook that hat caused some users to see the wrong Data Loss Prevention policy annotations in a multi-account profile. The build fixes a variety of bugs, including one in which an Excel file could not be previewed in File Explorer if the file’s extension included a capital letter such as XLSX or Xlsx, and one in which PowerPoint sometimes crashed when opening a file. (Access still supports Internet Explorer browser control.) This build offers several new features, including adding closed captions to audio objects in PowerPoint and web browser control for Edge in Access.
