PowerPoint Live Reactions Not Showing in Teams: Fix

You start a PowerPoint Live presentation in Microsoft Teams, but the reaction icons like hearts, claps, and laughs do not appear on screen for anyone. This problem usually occurs because of one of three root causes: the meeting organizer has disabled reactions, the presenter is using an older version of PowerPoint, or the presenter is sharing their screen instead of using the built-in PowerPoint Live feature. This article explains why reactions stop working, provides step-by-step fixes for each cause, and covers related failure patterns like missing reaction sounds or delayed icon display.

Why PowerPoint Live Reactions Fail in Teams Meetings

PowerPoint Live reactions rely on a specific chain of permissions and software versions. When any link in this chain breaks, reactions stop appearing. The three most common failure points are:

Meeting organizer disabled reactions in meeting options

Teams meeting options include a setting called Who can react. If the organizer set this to No one, no reaction icons will appear during any shared content, including PowerPoint Live. This setting overrides any presenter preferences.

Presenter is screen sharing instead of using PowerPoint Live

Reactions only work when the presenter selects the PowerPoint Live tab from the Teams share tray. If the presenter shares their entire screen or a specific window, Teams treats the content as a static video stream. The reaction engine cannot overlay icons on a screen share stream.

Outdated PowerPoint or Teams client

Microsoft introduced PowerPoint Live reactions in PowerPoint for Microsoft 365 version 2404 (Build 17531.20000) and Teams version 2.1.0.12345. Older versions of either application do not support the reaction feature. Users running perpetual licenses like PowerPoint 2021 or PowerPoint 2019 cannot use reactions at all.

Steps to Fix PowerPoint Live Reactions Not Showing

Follow these steps in order. Test reactions after each step by asking a meeting participant to click the heart or clap icon in the meeting toolbar.

Step 1: Check and update meeting reaction permissions

1. Open meeting details in Teams calendar
   Go to the Teams Calendar tab. Find the meeting where reactions are missing. Double-click the meeting to open its event details.
2. Edit meeting options
   At the top of the event details window, click Meeting options. This opens the meeting options page in your default browser.
3. Set Who can react to Everyone
   Scroll to the Who can react dropdown menu. Select Everyone. If you select Only me or No one, reactions will not appear for participants. Click Save.
4. Rejoin the meeting
   Leave the meeting and rejoin. The new reaction permission takes effect only after the meeting is restarted or after all participants rejoin.

Step 2: Share using PowerPoint Live instead of screen share

1. Open your presentation in PowerPoint
   Launch the PowerPoint file you want to present. Keep it open on your screen.
2. Click Share in the Teams meeting toolbar
   In the meeting controls at the top of the Teams window, click the Share icon (a rectangle with an upward arrow).
3. Select the PowerPoint Live tab
   In the share tray, you will see a section labeled PowerPoint Live. Click the thumbnail of your presentation. Do not select Screen or Window. The PowerPoint Live tab shows a small PowerPoint icon next to the presentation name.
4. Confirm reactions are enabled
   Once the presentation starts, look at the presenter toolbar at the bottom of the screen. You should see a reaction icon (a smiley face). If the icon is grayed out, reactions are disabled for this meeting. Return to Step 1 to check permissions.

Step 3: Update PowerPoint and Teams to the latest version

1. Check your PowerPoint version
   Open PowerPoint. Click File > Account. Under Product Information, look for Version and Build numbers. You need version 2404 (Build 17531.20000) or later. If you see Version 2309 or older, you must update.
2. Run Office updates
   In the same Account screen, click Update Options > Update Now. Wait for the update to download and install. Restart PowerPoint.
3. Update the Teams desktop client
   Click your profile picture in Teams. Select Check for updates. Teams will download and install the latest version. Restart Teams when prompted.
4. Test reactions again
   Start a new PowerPoint Live presentation using the steps in Step 2. Ask a participant to send a reaction.

If PowerPoint Live Reactions Still Have Issues After the Main Fix

Reactions appear but with a long delay

A delay of more than 3 seconds between a participant clicking a reaction and the icon appearing on screen is a network latency issue. Both the presenter and the participant should close bandwidth-heavy applications such as video streaming or large file downloads. The presenter can also switch to a wired Ethernet connection instead of Wi-Fi.

Reaction sounds play but icons do not show

If participants hear a chime when a reaction is sent but see no icon, the issue is a corrupted PowerPoint graphics cache. Close PowerPoint. Press Windows key + R, type %appdata%\Microsoft\PowerPoint, and press Enter. Delete the folder named Options. Restart PowerPoint and try sharing again. This resets the graphics rendering engine without affecting your presentations.

Reactions work for some participants but not others

This usually means the affected participants are using the Teams web app in a browser that blocks WebSocket connections. Have those participants install the Teams desktop app. The web app cannot maintain the persistent connection required for real-time reaction overlays. As a workaround, the presenter can enable the chat panel and ask participants to type reactions in the meeting chat.

PowerPoint Live Reactions: Presenter vs Participant Differences

Item	Presenter	Participant
Reaction visibility	Sees all reaction icons overlaid on slides	Sees all reaction icons overlaid on slides
Ability to send reactions	Cannot send reactions during own presentation	Can send reactions using the meeting toolbar
Reaction types available	N/A	Heart, Clap, Laugh, Surprised, Sad, Angry
Required software	PowerPoint for Microsoft 365 version 2404 or later, Teams desktop client	Teams desktop client or Teams web app (limited)
Permission dependency	Meeting organizer must set Who can react to Everyone	Meeting organizer must set Who can react to Everyone

After applying the fixes in this article, you can enable PowerPoint Live reactions in any Teams meeting where the organizer grants permission. The presenter must always use the PowerPoint Live tab in the share tray rather than a screen share. For the best experience, keep both PowerPoint and Teams updated to the latest available version. If reactions still fail after all steps, test in a new test meeting with only two participants to isolate the issue from a large group configuration.
