Has it ever happened that you know that a particular word is misspelled, but PowerPoint’s spell check doesn’t seem to think so! That may be because your word may be in all CAPS, or it may contain some numbers. In these cases, and in several other instances, PowerPoint just ignores any misspellings. Fortunately, you can turn off the options that instruct PowerPoint to ignore these misspellings. Remember though that changing these options will apply to all Microsoft Office 2016 applications you have installed on your computer including Word, Excel, and Outlook.
