Enable spell check in Microsoft Teams by opening Settings, selecting General, and turning on the Editor spellcheck toggle.
One wrong tap in a Teams message can send a typo to your whole team, and the fix is a single toggle hidden two menus deep. Enabling spell check in Microsoft Teams takes about ten seconds once you know where to look.
This guide shows how to enable spell check in Teams on desktop, web, and free versions, along with steps for adding languages, managing the dictionary, and fixing common issues when the toggle does nothing. The same setting works across all current versions of Teams.
Where Is The Spell Check Setting In Teams?
The spell check toggle lives under your profile menu in Settings, on the General tab, labeled Editor spellcheck. Microsoft moved it there in the current and new Teams interfaces, so the path is consistent regardless of which version you run.
On the desktop app, click your profile picture or More options (the three dots), select Settings, click General, and scroll to the bottom. The Editor spellcheck toggle is there. Turn it on, and Teams will underline misspelled words in your messages as you type.
On Teams Free the entry point is one menu deeper: click Settings and more next to your profile, then Settings → General → Editor Spellcheck.
Enabling Spell Check In Teams Desktop
The desktop setup is the most common scenario and follows a straight six-step sequence. After completing it, restart Teams if the change does not apply immediately.
- Open Microsoft Teams on your Windows or Mac computer.
- Click your profile picture in the top-right corner, then select Settings.
- In the left sidebar, click General.
- Scroll to the bottom of the General settings page.
- Toggle Editor spellcheck to On — the switch turns blue when active.
- Restart Teams completely (right-click the system tray icon and choose Quit, then reopen).
After restarting, type a message in any chat or channel. Misspelled words appear with a red squiggly underline. Right-click a flagged word to see suggested corrections.
Spell Check In Teams Free And New Teams
Teams Free users start from a different menu but reach the same toggle. Click Settings and more — the three dots beside your profile avatar — then Settings → General → Editor Spellcheck. The toggle works the same way once you turn it on.
In the new Teams interface (Teams 2.0), the layout is consolidated. Go to Settings → General and scroll to the bottom. The Editor spellcheck toggle sits in the same spot as the desktop version. If you use Teams in a browser at teams.microsoft.com, the same Settings path applies, though browser-based Teams depends more heavily on OS language settings for actual word checking.
| Teams Version | Settings Path | Note |
|---|---|---|
| Teams Desktop | Profile → Settings → General → Editor spellcheck | Restart required after enabling |
| Teams Free | Settings and more → Settings → General → Editor Spellcheck | Same toggle, different entry |
| New Teams 2.0 | Settings → General → scroll to bottom | Consolidated layout |
| Teams Web | Same as desktop path | Depends on OS language settings |
| Windows OS | Language & region → Typing → Autocorrect & highlight | Must enable OS-level spelling |
| macOS | System Settings → Keyboard → Text Input → Correct spelling | macOS toggle feeds into Teams |
| All versions | Restart required after toggle change | Change may not apply until restart |
Adding And Managing Spell Check Languages
Teams supports spell check in multiple languages, and adding one takes a few clicks. After opening Settings → General → Editor spellcheck, click Manage next to the language list. Select a language from the dropdown and choose Add.
You can also add languages while composing a message. Click More options — the three dots above the message box — and select Manage languages. Teams will then check spelling in all the languages you have added. For full details on language options and supported dialects, see Microsoft’s official spell check guide for Teams.
Microsoft notes that Teams deliberately ignores certain types of text: words in all uppercase, words containing numbers, and web or file addresses will not be flagged even if they are misspelled. This is by design, not a bug.
Why Is Spell Check Still Not Working?
Spell check in Teams usually fails for one of three reasons — the operating system language settings are incomplete, Teams was not restarted after the change, or cached user data is interfering. Start with the OS before trying heavier fixes.
On Windows, open Settings → Time & language → Language & region. Confirm your language is installed and that Basic typing is enabled under the language options. Then go to Settings → Typing and turn on Autocorrect misspelled words and Highlight misspelled words.
On macOS, go to System Settings → Keyboard → Text Input and enable Correct spelling automatically.
If the OS settings are correct but Teams still does not spell check, restart the application entirely — right-click the Teams icon in the system tray and choose Quit, then reopen. For persistent issues in the new Teams version on Windows 11, clearing the Teams cache often resolves the problem. In managed business environments, IT policy may override user settings. Contact your admin if local fixes do not work.
| Problem | Most Likely Cause | Quick Fix |
|---|---|---|
| Toggle is grayed out | IT policy restriction | Contact your Teams administrator |
| Toggle is on but nothing happens | OS language or typing not configured | Enable OS-level spelling per steps above |
| Wrong language being checked | Language not added in Teams | Open Manage and add the correct language |
| Some words not flagged | Uppercase, numbers, URLs ignored by design | This is normal — see Microsoft’s docs |
| Spell check stops after update | Stale Teams cache | Clear cache and restart Teams |
| Autocorrect not working | Feature still rolling out or disabled | Check for Teams updates; toggle is under General |
| Toggle missing from General tab | Running an outdated Teams version | Update Teams or switch to new Teams |
Dictionary Controls In Teams
When Teams flags a word you use often, add it to your personal dictionary. Right-click the underlined word and select Add to Dictionary. The word stops appearing as an error in every conversation. If you want to skip a single suggestion without adding the word permanently, choose Ignore All.
Microsoft does not support editing local dictionary files directly, and community workarounds involving file edits are not recommended. Stick with the right-click menu for all dictionary management.
One thing worth knowing: the dictionary is tied to your Teams account, so words you add on your desktop carry over to other devices where you sign in with the same account.
How The New Teams Autocorrect Feature Works
Microsoft began rolling out an autocorrect feature for Teams in late 2025, with general availability reached in January 2026 per roadmap item 534487. When enabled, autocorrect replaces common misspellings as you type, similar to the feature in Word or Outlook.
The autocorrect toggle is separate from the spell check toggle. In Settings → General, look for Correct words while typing. Turn it off if you prefer seeing suggestions without automatic replacement. The feature applies to Teams desktop on both Windows and macOS.
Quick Reference: Teams Spell Check Setup
- Open Teams Settings → General → Editor spellcheck and toggle it on.
- Restart Teams to activate the change.
- On Windows: verify Basic typing and the highlight/autocorrect toggles under Language & region.
- On macOS: enable Correct spelling automatically under Keyboard → Text Input.
- Add additional languages via Manage in the spell check settings.
- Right-click flagged words to add to dictionary or ignore a suggestion.
- If nothing works, clear the Teams cache or contact your IT administrator.
