Restore core functionality for Office 2019

Question

I purchased Office Home & Business 2019 directly from Microsoft and installed it on my MacBook with an M1 Pro chip in 2021. As of July 13, 2026, I can no longer create or edit documents using Office.

The software was advertised as a one-time purchase, so I expected to retain access to its core functionality. Losing the ability to create and edit documents appears inconsistent with that expectation and with the spirit of the license agreement.

Please explain why this functionality is no longer available and how it can be restored under my existing license.

Answer 1

Hello,

Starting July 13, 2026, Office 2019 for Mac entered reduced functionality mode because its licensing certificate can no longer be updated. Office may still open documents, but it can no longer activate for editing, saving, or creating files..

Microsoft confirms that Office 2019 for Mac cannot be updated to the required version, and reinstalling Office 2019 will not resolve it.

The available options are:

1. Use Word, Excel, and PowerPoint online for free through Microsoft 365 for the web.
2. Purchase a supported version such as Office Home 2024.
3. Subscribe to Microsoft 365.

Your existing documents are not deleted or damaged, but Office 2019 for Mac can no longer be restored to full editing mode through activation troubleshooting. This is only affecting this version on macOS, but this license can still work with full features on Windows devices.
