Launch your Microsoft Office application (like Word), click on 'File' in the top-left corner, and select 'Options' at the bottom of the menu.

2
Access Proofing Settings

In the Word Options dialog box, click on the 'Proofing' tab located on the left sidebar.

Disable Spelling and Grammar

Scroll down to the 'When correcting spelling and grammar in Word' section. Uncheck 'Check spelling as you type' and 'Mark grammar errors as you type'.

Frequently Asked Questions

Can I completely remove Microsoft Editor from Office?

No, Microsoft Editor is deeply integrated into Microsoft 365 and cannot be fully removed. However, you can effectively disable its presence by turning off spelling and grammar checking in the Proofing settings.

Why do I see both Grammarly and Word underlines at the same time?

This occurs when both Grammarly and Microsoft Editor are actively scanning your text. Disabling Word's native 'Check spelling as you type' feature in the Options menu resolves this overlap.

Who do I contact if Grammarly stops working in Word?

Since Grammarly is a third-party non-Microsoft product, you should contact Grammarly Support directly for any issues specific to their add-in or desktop application functionality.
