Where to find the language setting in Outlook

The language setting in Outlook lives in a different place depending on whether you use the desktop version or the web version. On the desktop app for Windows or Mac, go to File in the top left, then Options (Windows) or Preferences (Mac). On the web version at outlook.com or outlook.office.com, click the gear icon in the top right corner, then View all Outlook settings.

Once you are in the settings area, look for Language or Regional options. The exact name and location shift slightly between versions, but the principle is the same: Outlook stores language preference in the general settings, not in a separate menu.

Key Takeaways

  • Desktop Outlook uses File > Options (Windows) or File > Preferences (Mac) to reach language settings; the web version uses the gear icon and "View all Outlook settings".
  • Changing the language in Outlook changes the interface language only — the language of menus, buttons, and help text — not the language of your emails themselves.
  • Some language packs read automatically when you select a new language; others require a restart of Outlook to take effect.
  • If you use Outlook through Microsoft 365 at work, your organization may have locked the language setting, and you will need to contact your IT department to change it.

Steps for desktop Outlook on Windows

Open Outlook and click File in the top left corner. From the menu that opens, select Options. In the Options window, click Language on the left side. You will see a dropdown menu labeled Display Language or Office Language Preferences.

Click the dropdown and scroll to find the language you want. Select it, then click OK or explore. Outlook will prompt you to restart the process for the change to take effect. Close and reopen Outlook, and the interface will appear in your chosen language.

Steps for desktop Outlook on Mac

Open Outlook and click Outlook in the menu bar at the very top of the screen. Select Preferences from the dropdown. In the Preferences window, look for General or Language. Click on it.

Find the Language dropdown and select your preferred language from the list. Close the Preferences window. Outlook may restart automatically, or you may need to close and reopen it manually. The interface language will change the next time the process opens.

Steps for Outlook on the web

Go to outlook.com or outlook.office.com and sign in. In the top right corner, click the gear icon. From the menu, select View all Outlook settings. Click General on the left side of the settings page.

Scroll down to Language and time zone. Click the Language dropdown and choose your language. Scroll to the bottom of the page and click Save. The web interface will refresh and display in your new language when ready — no restart required.

What changes and what does not

Changing the language in Outlook changes only the interface language — the words on buttons, in menus, and in help text. It does not change the language of your emails, contacts, or calendar entries. If you write an email in English, it will remain in English even if you switch Outlook's interface to Spanish.

The spell-check language may also change automatically when you switch the interface language, depending on your version. If you want spell-check in a different language than your interface, you can usually set that separately in the same settings area.

When the language setting is locked by your organization

If you use Outlook through a work Microsoft 365 account, your IT department may have restricted the language setting so that all users see the same interface. If you cannot find the language option, or if the dropdown is grayed out and unclickable, the setting is locked.

Contact your IT support team or help desk and ask them to change the language setting for your account. Provide them with the language you want to use. They can make the change from their end, and it will take effect the next time you sign in.

Troubleshooting when the language does not change

If you selected a new language but the interface did not change, the most common reason is that you did not restart Outlook after saving. Close the process completely — not just minimizing it — and open it again. On Windows, you can check the Task Manager to make sure no Outlook process is still running in the background.

If the language still has not changed after a restart, try signing out of your Microsoft account within Outlook and signing back in. On the web version, try clearing your browser cache and cookies, then sign in again. If neither works, contact Microsoft Support or your organization's IT department.

Frequently Asked Questions

Does changing Outlook's language change the language of my emails?

No. The language setting changes only the interface — menus, buttons, and labels. Your emails stay in whatever language you write them in. If you need to write in a different language, you can do that regardless of what language Outlook's interface is set to.

Can I use Outlook in two different languages on the same computer?

Not simultaneously. Outlook has one language setting per account. If you have multiple Microsoft accounts on the same computer, each account can have its own language setting, but you will need to sign out and sign back in to switch between them.

What if my language is not in the dropdown list?

Outlook supports most major languages, but some regional or minority languages may not be available. Check whether a similar language is listed — for example, "Spanish (Mexico)" instead of a specific regional dialect. If your language truly is not available, you may need to use English or another supported language.

Will changing the language affect my calendar or contacts?

No. Your calendar entries, contact names, and all your data remain unchanged. Only the words that Outlook uses to label features and buttons will appear in the new language.

Do I need to change the language on my phone version of Outlook too?

The Outlook mobile app (on iPhone or Android) uses the language setting of your phone itself, not a separate Outlook setting. To change the language on mobile, go to your phone's system settings and change the device language there.
