Frequently Asked Questions

Why did spell check stop working in my Word comments?

Microsoft recently introduced the 'Modern Comments' feature to its desktop apps (such as Mac version 16.63.1). This new interface currently lacks the native ability to spell-check text inside the comment bubbles, unlike the older classic comments.

Can I disable Modern Comments to get spell check back?

Depending on your specific version of Word, you may be able to revert to classic comments. Go to Word Options (or Preferences on Mac) > General, and look for a checkbox labeled 'Enable modern comments'. Unchecking this and restarting Word may restore classic comments and spell-check functionality.

Does spell check work in older versions of Word?

Yes. The classic comments feature found in older versions of the Microsoft Word desktop application fully supports spell-checking. The issue is strictly isolated to the newer Modern Comments update.
