Insider Fast – Check out the new look and improved functionality for mail and meeting invite headers


Starting with this week's Insider Fast release (15.38.170822), we have a new look as well as improved functionality for Outlook's mail and meeting invite headers.


Why are we doing this?

We are re-designing our mail and meeting invite headers to improve readability, accessibility as well as feel more modern and at home on the Mac platform.


Here are some key highlights:  

  • Improved keyboard navigation support making it easier to navigate the header without a mouse
  • Improvements to VoiceOver and tweaks to contrast ratios to improve readability
  • Improvements to readability by presenting a view of recipients that is easier to read at a glance
  • The addition of a Show Details button to reveal additional information on who's on To: and who's on Cc: should you so desire


To navigate the new headers with a keyboard you can use:

  • Tab to move in-between the From and Recipient Fields
  • Left And Right Arrow keys to move between recipients
  • Shift-F10 To open the context menu on a selected recipient
  • Space bar to select between Show and Hide Details, when the selection is on the Show or Hide Details Button
