How to fix Outlook language change

Question

My outlook randomly changed into Vietnamese.

I have changed the language in the settings menu and my folder list is now back to English but the menu bar / ribbon at the top is still in Vietnamese?

Answer 1

Hi

Since the folders are back in English but the ribbon is still Vietnamese, the Office display language is most likely still set to Vietnamese.

In classic Outlook, go to File > Options > Language. Under “Office display language”, select English and click “Set as Preferred”. Make sure English is at the top, then close all Office apps and restart the PC. Microsoft’s instructions are here: https://support.microsoft.com/en-us/outlook/getstarted/manage-language-settings-in-outlook

If the ribbon is still Vietnamese, repair Office via Settings > Apps > Installed apps > Microsoft 365 > Modify > Quick Repair. If needed, try Online Repair: https://support.microsoft.com/en-us/office/lifecycle/repair-an-office-application

Please let me know whether English is shown as “Preferred” under Office display language.
