Why Spell Check Stops Working in Microsoft Teams

If spell check is not working in Microsoft Teams, typing messages can become frustrating very quickly. Misspelled words may not be highlighted, or autocorrect may stop working entirely while chatting or composing messages.

This guide explains why spell check may not be working in Microsoft Teams and how to fix the issue on Windows step by step.

Why Spell Check Stops Working in Microsoft Teams

Spell check issues in Teams are usually related to app settings, language configuration, or browser and app glitches.

Common causes include:

• Spell check disabled in Teams settings
• Incorrect language selected
• Outdated Teams app
• Browser issues when using Teams on the web
• Corrupted app cache

Understanding the cause helps apply the correct fix faster.

Check Spell Check Settings in Microsoft Teams

Spell check can be turned off accidentally.

To enable it:

1. Open Microsoft Teams
2. Click your profile picture
3. Select Settings
4. Go to General
5. Make sure Enable spell check is turned on

Restart Teams after enabling the option.

Check Language Settings in Teams

Spell check works based on the selected language.

To check language settings:

1. Open Teams Settings
2. Go to General
3. Under Language, choose the correct language
4. Restart Teams to apply changes

If the wrong language is selected, spell check may not work correctly.

Restart Microsoft Teams

Temporary glitches can disable spell check.

Try this:

• Fully close Microsoft Teams
• Make sure it is not running in the system tray
• Reopen the app and test spell check again

A restart often fixes minor issues instantly.

Clear Microsoft Teams Cache

Corrupted cache files can break spell check functionality.

To clear cache:

1. Close Microsoft Teams
2. Press Windows + R
3. Type %appdata%\Microsoft\Teams
4. Delete all files and folders inside
5. Restart Teams

Your chats and data will not be deleted.

Update Microsoft Teams

An outdated Teams version may cause features to stop working.

To update:

• Click your profile picture in Teams
• Select Check for updates
• Allow Teams to download and install updates

Restart Teams after the update completes.

Check Browser Spell Check (Teams Web Version)

If you are using Teams in a browser, spell check depends on browser settings.

Make sure:

• Browser spell check is enabled
• The correct language is selected in the browser
• Extensions are not interfering

Try using a different browser to confirm.

Reinstall Microsoft Teams

If nothing works, reinstalling Teams can fix deep issues.

Steps:

1. Uninstall Microsoft Teams from Settings
2. Restart your PC
3. Download and install the latest Teams version
4. Sign in again

This resets all settings to default.

Final Thoughts

Spell check not working in Microsoft Teams is usually caused by disabled settings, language mismatches, or corrupted cache files. In most cases, enabling spell check, restarting Teams, or clearing the cache resolves the issue quickly.

Keeping Teams updated helps prevent similar problems in the future.
