If Microsoft Teams emojis are not working, first check whether the issue is with inserting an emoji, reacting to a message, or using your organization’s custom emoji. Try the emoji picker and a shortcode such as :smile:, then test Teams on the web; if the problem is limited to the desktop app, reset the local data for the Teams version you use.

First, check which emoji feature is failing

Teams has separate controls for inserting an emoji into your message, reacting to someone else’s message, and using custom organization emoji. A problem with one does not necessarily affect the others.

What is not working? Correct Teams control
Adding an emoji to your own message Emoji, GIFs and Stickers in the compose box
Reacting to a message Hover over the message and choose a quick reaction or More reactions
Using a company-specific emoji Emoji, GIFs and Stickers → Emoji → Your org’s emoji
Creating custom memes or stickers Use Teams on desktop or the web; Microsoft does not document a creation path in the iOS or Android app

Quick fixes for Teams emojis

  1. Confirm that you are in the compose box. In a chat or channel, select Emoji, GIFs and Stickers beside the message box. Choose an emoji from the gallery or search for one, then select Send.
  2. Try a shortcode. Click in the compose box and type a colon followed by the emoji name, such as :smile:. Select a suggestion or press Enter to insert the top match. This can help distinguish a picker issue from a broader sending problem.
  3. Try Teams on the web. Test the same chat or channel in a supported browser. If emojis work there but not in the desktop app, the local app or its installation may be the issue.
  4. Restart Teams completely. Quit the application rather than merely closing the current chat, then reopen it.
  5. Check another conversation. Test a one-to-one chat and a channel message. If the picker fails everywhere, investigate the app; if it fails only in one location, an account, policy, or conversation-specific issue may be involved.
  6. Update or reinstall Teams if the problem persists. An outdated or damaged installation can prevent interface components from loading correctly.

How to add an emoji on mobile

In the Teams app for iPhone or Android, tap Emoji beneath the compose box. Choose a gallery, then choose the emoji. Microsoft lists galleries including Smilies, Hand gestures, People, Animals, Food, Travel and places, Objects, Activities, and Symbols.

Teams reactions are not the same as inserted emojis

To react to a message in the desktop or web app, hover over it and select a quick reaction. Select More reactions to see the full list. Teams supports up to 20 reactions per message. Selecting a reaction you already added removes your reaction.

When recent emojis or reactions are missing

Microsoft’s current documentation says recently used emojis and reactions sync between desktop and mobile. An empty or inconsistent Recent list is therefore not the documented normal behavior once synchronization has reached your account.

  2. Go to Apps → Installed apps.
  3. Search for Microsoft Teams.
  4. For New Microsoft Teams, select the … button.
  5. Choose Advanced options.
  6. Under Reset, select Reset.

  1. Quit Teams completely.
  2. Press Windows + R.
  3. Enter this path: %userprofile%\appdata\local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams

Recommended troubleshooting order

  1. Test the normal picker and a shortcode such as :smile:.
  2. Test a different chat or channel.
  3. Try Teams on the web or on mobile.
  4. Restart Teams and verify that you are using the correct account.
  5. Reset local data using the instructions for New Teams or classic Teams.
  6. Ask your administrator about custom emoji, reactions, or messaging policies.

This sequence helps distinguish a temporary interface failure from a local-data issue or an organization-level restriction.

The Bottom Line

Distinguish inserted emojis from reactions and custom organization emoji. Test the picker and a shortcode, try another Teams client, and then reset the correct local data for New Teams or classic Teams. If standard emoji work but custom emoji or reactions do not, ask your Teams administrator about policy restrictions.

FAQ

Why is the Teams emoji picker not opening?

Restart Teams, test a shortcode such as :smile:, and try Teams on the web. If the web version works, reset local data for your Teams client using the instructions for your version.

Why can I use emojis but not reactions in Teams?

Emoji insertion and message reactions use different controls. Hover over the message and choose a quick reaction or More reactions. On mobile, touch and hold the message, then tap a reaction.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Why are my recent Teams emojis different on my phone and computer?

Microsoft documents synchronization of recently used emojis and reactions across desktop and mobile. Check that both clients use the same account, sign out and back in, and reset the affected client if the lists remain inconsistent.

Can I create custom Teams emojis on my phone?

Microsoft documents custom emoji creation through the desktop or web app. Its mobile instructions do not provide a path for creating custom memes or stickers.

Will clearing the Teams cache delete my chats?

The cache procedures remove local Teams files, not the server-held chat history. The New Teams Windows Reset option deletes app data, including personalization settings, so you may need to restore preferences afterward.
