How to Stop Word Spell Check Language from Turning Off
Question details
The user needs to prevent Microsoft Word or Outlook from automatically disabling the spell and grammar check feature while typing.

- Product
- Microsoft Word / Outlook
- Device & OS
- not provided
- Scenario
- Typing or editing a document where the spell check unexpectedly stops functioning and formatting changes automatically.
- Observed behavior
- Word or Outlook automatically selects 'Do not check spelling or grammar' due to automatic language detection, making the spell check appear to turn off repeatedly at the insertion point.
Ensure you have your problematic document open in Word or your message open in Outlook so you can access the Review tab.
Disable Automatic Language Detection in Proofing Settings
Turning off automatic language detection prevents Word from changing proofing languages at the insertion point, ensuring spell check stays active.
Microsoft Word and Outlook treat proofing languages as character-level formatting. When 'Detect language automatically' is enabled, typing a word that the system identifies as another language can cause it to silently toggle 'Do not check spelling or grammar'. Disabling this automatic detection forces the application to stick to your chosen default language.
Navigate to the 'Review' tab on the ribbon menu, click on 'Language' in the Language group, and select 'Set Proofing Language'.
In the Language dialog box that appears, locate and uncheck the box next to 'Detect language automatically'.
Select your preferred language from the list above, click 'Set As Default' if you want this to apply to all future documents, and then click 'OK'.

Frequently Asked Questions
Why does my spell check turn off automatically in Word?
This typically happens because Word's 'Detect language automatically' feature is enabled. When Word thinks you are typing in a different language, it may switch the proofing language or apply a 'Do not check spelling or grammar' format to that specific block of text.
How do I force Word to spell check my entire document?
Press Ctrl+A to select all the text in your document. Then, go to Review > Language > Set Proofing Language, ensure your preferred language is selected, uncheck 'Do not check spelling or grammar', and click OK. Finally, press F7 to manually run the spell check.
Does this spell check issue affect Microsoft Outlook as well?
Yes, because Outlook uses Word's authoring engine for composing emails. You can fix it in Outlook by navigating to Review > Language > Set Proofing Language while writing an email and disabling automatic language detection.
Is changing the proofing language a document-wide setting or character-level?
In Word, proofing language acts as character-level formatting. This means a single document can have multiple languages applied to different words or paragraphs, which is why automatic detection can cause inconsistent spell check behavior if it misinterprets your typing.
