Hi @Venla Urponen,
Welcome to Microsoft Q&A forum.
Thank you for reaching out and sharing the details of your situation. What is most likely happening is that Microsoft 365 and OneDrive are not strictly following the current Windows display language. When the device language was previously set to German, that preference was saved at the Microsoft account and application level. Changing Windows back to Finnish does not always automatically update those services.
Please follow the steps below in order, as each layer can affect the language used by Office and OneDrive.
- Confirm the Microsoft account language
- Sign in at https://account.microsoft.com.
- Open Your info and then Settings & Privacy.
- Set Finnish or English as the primary language.
- Remove German if it is listed.
- Save the changes and sign out.
- Reset Office language settings
- Open an Office app such as Word.
- Go to File, Options, Language.
- Under Office display language, set Finnish or English as preferred.
- Repeat the same under Office authoring languages.
- Close and reopen the Office app.
- Reset OneDrive settings
- Press Windows key + R and run wsreset.exe.
- Restart the computer.
- Check Windows regional settings
- Go to Settings, Time & Language, Language & Region.
- Set Country or Region to Finland.
- Set Regional format to Finnish.
- Restart the device.
