Office 2019 for Mac Enters Reduced Functionality Mode July 13
Key Takeaway: Starting July 13, Office 2019 for Mac will enter reduced functionality mode, disabling creation, editing, and saving of documents due to an expiring digital certificate.
What Is Happening
Starting July 13, Office 2019 for Mac will enter reduced functionality mode, disabling creation, editing, and saving of documents. The change is due to an expiring digital certificate.
Affected Apps
The affected apps include Word, Excel, PowerPoint, Outlook, and OneNote. Users can still open, view, and print existing documents.
Why This Is Happening
The certificate was renewed by Microsoft, but the update is only available in version 16.83, which is not provided to Office 2019 users because Microsoft ended support for Office 2019 on October 10, 2023. Reinstalling Office 2019 will not resolve the issue.
What Microsoft Recommends
Microsoft recommends affected users:
- Switch to Microsoft 365 web apps
- Subscribe to Microsoft 365
- Purchase Office 2024
Who Can Still Update
Supported versions of Office on macOS 12 Monterey or later can be updated to build 16.83. iPhone and iPad users on iOS 17 or later need build 2.93.
Looking Ahead: Office 2021 Support Timeline
Office 2021 support ends on October 13, 2026; after that, apps will function but receive no security or feature updates.
