-
Automatic grammar checking is available only in Outlook, Word, and PowerPoint.
Office marks potential spelling errors with a red squiggly line, and potential grammatical errors are marked with a blue squiggly line.
If spelling or grammatical errors aren't marked, automatic checking might be turned off. You can turn on the automatic spelling and grammar checker.
When you see a spelling or grammatical error that you want assistance fixing, right-click on the underlined word or phrase and choose one of the options to fix the error.
If Office is flagging words as misspelled but you have it spelled the way you want it, select Add to Dictionary to teach Office not to flag that word as misspelled in the future. For more information on this see: Add or edit words in a spell check dictionary.
