If you use an older Mac, iPhone or iPad, Microsoft might be about to break your Office apps. Starting July 13, Word, Excel, PowerPoint, Outlook and OneNote will stop letting you edit, save or create new files unless you meet certain requirements. You’ll still be able to open and print documents, but that’s it.
The move affects more people than you might think. If you’re running anything older than iOS 17 or macOS 11 Big Sur, your Office apps will mostly be defunct. Microsoft calls it “reduced functionality mode,” which is a fancy way of saying your Office apps will lose editing functionality.
