Microsoft has released a new Office Build for Office Insiders on Windows. The new Build 12920.20000 includes a number of new features for Outlook and PowerPoint, and it also comes with fixes for bugs in Word, Excel, PowerPoint. You can read the official changelog below.


Feature updates


  • Additional buttons added to Outlook toast notifications: Quick Action buttons now appear in Outlook toast notifications when running Outlook on Windows 10.


  • Improved Stream video performance in PowerPoint: We’ve made improvements to the playback performance of Microsoft Stream videos to minimize video loading time and create a smooth viewing experience. Use your corporate videos from Microsoft Stream to create better presentations.

Resolved issues


  • We fixed an issue where Excel would occasionally shut down when engaging OneDrive.
  • We fixed an issue where clicking a bookmarked hyperlink within the same workbook would cause the workbook to be hidden.
  • We fixed an issue where some copy and pasted chart links used mapped drive addresses rather than universal addresses.
  • We fixed an issue where Excel could become unresponsive after using Ctrl+Shift+Arrow keys to scroll when the Excel window was shared through Teams.


  • We fixed an issue where slides were not centered after zooming using the mouse wheel.


  • We fixed an issue where copy and pasting text to a comment pane would not be displayed.
  • We fixed an issue where comment hint bubbles appeared blurry at 100% zoom.
  • We fixed an issue where enabling policy Word 2007 and later Binary Documents and Templates would cause some co-authoring cases to fail.
  • We fixed an issue where files with long path names (greater than 32K) would not open and an appropriate error message was not being displayed.
