The Spell Checker feature in Office 365 helps users with their grammar and is available in Outlook, Word, PowerPoint, and Excel, so if your writing is not superior, this feature available in your Microsoft Office programs is helpful. When opening the spelling dialog box or pane, it consists of options to change, ignore, and add words to the Office dictionary. Sometimes users may not want to see the redlines all the time, which indicates that there is an error due to having an add-in grammar checker, for example, Grammarly, and they don’t want to see the Spell-checker red line along with the Grammarly Correctness checker and they want it to be disabled.
