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. For details, see Release notes for Microsoft Office security updates. It also fixes a number of security holes. This build fixes several bugs, including one in Outlook that caused users of the Event-Based feature to be unable to utilize some of the new APIs included in Mailbox Requirement Set 1.13, and one in Project in which users were unable to connect Project Client from the desktop to a Project Web Access site in Project Server 2016. It also fixes a variety of bugs, including one in Excel in which Conditional Formatting rules were not being preserved after closing and reopening a workbook, one in Outlook in which people were shown the error “We cannot render Actionable Messages right now” when reading some email messages, and one in Access in which refreshing an ODBC connection to an Access database caused the operation to stop working after refreshing the link several times. This build offers faster filtering when cells contain unique or duplicate rules in Excel, as well as a new accessibility ribbon tab in Outlook and PowerPoint for making emails and presentations more accessible. 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.
