Hello Gordon Nelson,
Thank you for posting to the Microsoft Q&A forum.
I can understand how alarming and confusing it is to open your inbox and suddenly see all your folders in an entirely different language that you do not recognize. When language settings change without your intervention, it is unfortunately a strong indicator that an unauthorized party may have accessed your account.
To revert your inbox back to normal and secure your account, please follow the steps below.
Note: Because your interface is currently in a foreign language, the text on your screen will not match the English instructions below. However, the menu positions and icons are exactly the same, so just use the icons to guide you. Also, based on which language was selected, your screen might be mirrored (for right-to-left languages), so your menus and scrollbars could be on the opposite side of the screen.
Step 1: Change the Language Back to English
- Click the Gear icon (Settings) in the top corner of the screen.
- Go to General (usually the 2nd option on the left sidebar, often with a gear or slider icon) > Language and time.
- Change the first drop-down menu back to English.
- Make sure to check the box just below the language selection to change the folder names so they match the new language.
- Click Save at the bottom of the menu.
- Refresh your browser page. Your layout should now be back to normal.
Step 2: Check for Unrecognized Rules and Forwarding Since someone else likely changed this setting, it is critical to ensure they didn't leave behind any hidden rules to forward your private emails.
- Click the Gear icon (Settings) in the top right corner.
- Go to Mail > Rules and delete any rules you do not recognize.
- Go to Mail > Forwarding and ensure automatic forwarding is turned off.
If you still cannot find the correct settings because of the foreign text, please feel free to send a screenshot of your screen so I can instruct you step by step.
Note: please remember to remove any Personally Identifiable Information (such as email, full name, your image, phone number,.....) for security purpose.
I hope this helps you get your inbox back into English and fully secures your account. Please feel free to reply if you need further assistance!
