Starting from July 13, 2026, Microsoft will no longer allow you to edit documents in Microsoft Office 2019 for Mac. The company attributes the change to the expiration of the digital certificate for its suite of productivity apps (via JimmyTech).
When your Microsoft Office 2019 for Mac license expires, the apps enter reduced functionality mode. That means you’ll still be able to open, view, and print existing documents in Word, Excel, PowerPoint, Outlook, and OneNote. However, you’ll lose the ability to create new files, edit content, or save changes.
