Now in public preview: New Content Sharing Tray



We are improving the user experience of sharing content in a meeting. The new Share Tray seeks to improve users’ ability to understand each content type and share the right content in their meetings.  


Flighting status          

Started flighting today. Rollout estimated to complete by the end of this week.


How to enable


The new share tray allows you to share everything you could in the old share tray, the only difference is the form factor and user experience of finding the content you need to share. We’ve streamlined the experience to make it easier to find what you’re looking for, and hopefully less overwhelming and cluttered.

  1. Select a Screen to share your entire screen. If you have 2 screens (i.e. monitors) you’ll see them listed on the first page of the Share Tray. If you have 3 or more screens attached, you’ll see a More button to view a list of all the screens you can share.




  1. Select the Window tile to see a list of all the Windows you have open. Select one of the windows to start sharing. Note that Window sharing offers a more private sharing experience; meeting participants won’t be able to see any notifications that might overlay your screen. 
  2. Use PowerPoint Live to share a PowerPoint file using the new and improve live sharing experience. You can select the file from the Most Recently Used list of files in the share tray, or upload one from your computer or your OneDrive.
  3. Select Include Computer Sound to share your computer’s sound when sharing a Screen or Window. Note that computer sound does not apply to other content types. PowerPoint Live uses a different technology stack to ensure any embedded audio/video in the PPT deck is shared. You don’t need to toggle computer sound on if you are using PowerPoint Live and sharing embedded audio or videos in your deck.
  4. Select FreeHand by InVision to share InVision’s whiteboarding product for participants to use in the meeting. Note that this may not be shown in the share tray if your tenant hasn’t enabled InVision for its users.
  5. Select Microsoft Whiteboard to start sharing a whiteboard in your meeting. Everyone will be able to draw on the whiteboard and you can access the whiteboard after the meeting from the Whiteboard tab from the meeting detail page or meeting chat. 

Note: If you need information about enabling the public preview itself, see “Enable the public preview for Teams” below.

Love the updates! Will be so much easier for people to find and select what they want to share...especially those who are a bit overwhelmed by everything Teams can do!

I have not got this functionality yet in public preview. I have updated Microsoft 365 apps to 2104 and have also updated my Teams client to Version (64-bit).

@Kaushal Mehta (LYNC) Can I share more than one window at the same time?

What is the time delay between the public preview and the public official release of a feature ? The idea is to know how long time our IT teams have to test and document new features before they are widely added in teams in our organization?
