Starting July 13, 2026, Microsoft 365 subscribers on macOS, iPhone, and iPad, and those with non-subscription software, including Office 2021 or Office 2019 on macOS might notice that Office apps (Word, Excel, PowerPoint, Outlook, or OneNote) can open and print files, but cannot edit, save, or create new files – called “reduced functionality mode”. For more information, go to Update Microsoft 365 or Office on your macOS or iOS device.
