Hello, thank you for reaching out to Microsoft Q&A.

Microsoft periodically updates its certificates used to sign Office applications and validate Microsoft 365 licensing.

Here,

Office 2019 for Mac reached the end of support on October 10, 2023, and no longer receives updates. Because it cannot be upgraded to the latest version, this issue cannot be resolved by updating or reinstalling Office 2019.

Going forward, if your Mac is running macOS 12 (Monterey) or later, you will need to either upgrade to Office 2024 or purchase a Microsoft 365 subscription to continue using Office desktop apps on your Mac.

does it mean I should purchase another Microsoft office or subscription?

Yes, you can purchase the latest one-time-purchase version of Office, such as Office Home 2024, which includes Word, Excel, PowerPoint, and OneNote.

If you'd also like Outlook and OneDrive (1TB Cloud Storage) along with the premium desktop Office apps, a Microsoft 365 subscription would be the better fit.

If you only need Outlook in addition to Word, Excel, and PowerPoint (without OneDrive or a subscription), you can go with Office Home & Business 2024 instead.

Also, make sure you're running the latest version of MacOS.

As of September 2025, the three most recent major versions are macOS Tahoe (26), macOS Sequoia (15), and macOS Sonoma (14).

Answer 2

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. The 0x0 error is part of that activation failure.

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:

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