The user needs to prevent OneNote from using the incorrect proofing language for spell check when typing notes.

How to Fix OneNote Using the Wrong Proofing Language on Windows 11
Product
Microsoft OneNote
Device & OS
Windows 11
Scenario
Editing or typing text in OneNote where a specific non-English proofing language, such as German, is required.
Observed behavior
OneNote continuously defaults to or reverts to English proofing tools, ignoring the user's manual language selection within the application.
Before you start

Ensure your Windows 11 system is fully updated and that you have downloaded the necessary language packs for the specific proofing language you intend to use.

Solution 1Recommended

Match the Windows Keyboard Layout to Your Proofing Language

Use this recommended solution to align your system keyboard settings with OneNote, preventing the app from automatically reverting to English spell check.

OneNote automatically detects your active Windows keyboard language and links it directly to the proofing language. If your system keyboard remains set to English while you type in German, OneNote will force English proofing tools on the text.

1
Open Windows Language Settings

Click the Start button, select 'Settings', and navigate to 'Time & language' on the left sidebar. Click on 'Language & region'.

2
Add the Desired Language

Under the 'Preferred languages' section, click the 'Add a language' button. Search for your desired language (e.g., German), select it, and click 'Next' to install the language pack.

3
Switch Keyboard Layouts

Before you begin typing in OneNote, press the 'Windows key + Spacebar' to toggle your active keyboard layout to the newly installed language. OneNote will now automatically use this language for proofing.

Match the Windows Keyboard Layout to Your Proofing Language
Display Language Unaffected: Changing the active keyboard layout for proofing does not change your Windows 11 display language. Your menus and apps will remain in English.

Frequently Asked Questions

Why does my OneNote proofing language keep changing back to English as I type?

OneNote is designed to automatically detect and match the active Windows keyboard layout. If your Windows keyboard is set to English, OneNote will continuously switch the proofing language back to English every time you type a new word, regardless of the language you manually selected in the app.

Can I change the OneNote proofing language without changing my Windows display language?

Yes. Windows 11 separates display languages from keyboard layouts. You can keep your system and app menus entirely in English while adding a German or French keyboard layout. Toggling to this layout using Win + Space only affects typing and proofing, not the display language.

Does this proofing language issue affect the Windows 10 version of OneNote?

Yes, this behavior is built into the core functionality of both OneNote for Windows 10 and the OneNote desktop app. In both versions, the proofing language is inherently tied to the operating system's active input method or keyboard layout.
