Using New Outlook on Windows for personal email, calendar, and contact management
Hello Chanwoo Park2,
Thank you for posting this case in the Microsoft Community!
Based on your description: Translator is showing an error in Outlook for Windows. I would like to cooperate with you to work on this case. To clarify this case, it seems that you are using Classic Outlook for Windows as your captured screenshot. Please confirm if you are using Classic Outlookor New Outlook. For my suggestion, if using classic Outlook for Windows, please kindly check the following workaround to fix this case step by step:
- First, you may try to restart your Outlook and Windows systems to test again if the Translator feature is working or not. Please also check if the target language has been installed and set as default in the Outlook client by going to Outlook>File>Outlook Options>Language>Translation.
- If not working, please review this page and see if the guidance helps: Modern Translator in Microsoft 365 - Microsoft Support.
3. Outlook works best when it's up to date. We recommend setting Windows Update to automatically download and install recommended updates. Bug fixes, new features, and performance enhancements are released regularly. To install the latest Windows and Office updates, see Install Office updates.
- Then you may try to re-create another Outlook profile and test it again. Create an Outlook profile - Microsoft Support
- If this case persists, finally, you may try to re-install the latest version of the Office 365 application and check if working or not.
Download and install or reinstall Microsoft 365 or Office 2021 on a PC or Mac - Microsoft Support
Hope the above workaround will be helpful. If you need further assistance, please let me know, and I will keep assisting you.
Your understanding and patience will be appreciated.
Thank you!
Sincerely,
