TL;DR
Microsoft is set to restrict offline functionality of Office 2019 and 2021 for Mac and iOS devices on July 13, 2026, due to license validation certificate expiration. Users can only view files unless they update or switch to Microsoft 365. The move raises concerns about user rights and product longevity.
Microsoft will disable full offline functionality of Office 2019 and 2021 for Mac and iOS devices starting July 13, 2026, due to the expiry of a license validation certificate. This change affects users who rely on perpetual licenses and raises questions about product support and user rights.
Microsoft announced that, after July 13, 2026, Office 2019 and 2021 for Mac and iOS will enter a ‘reduced functionality mode’ when offline. In this mode, users can open and view files but cannot edit, save, or access full features. The change is triggered by the expiration of a digital certificate used for license validation, which cannot be renewed for Office 2019 due to product limitations.
Microsoft’s support documentation states that only updated versions of Office 2021 and Microsoft 365 apps will continue to function normally after the deadline, as they include renewed certificates. Office 2019, which reached end of support in October 2023, has no update path to avoid this change. Microsoft has begun notifying affected customers via email, offering options such as switching to web apps, subscribing to Microsoft 365, or purchasing a new perpetual license.
Why It Matters
This move impacts users with perpetual licenses for Office 2019 and 2021, potentially forcing them to upgrade or switch to subscription-based services. It raises concerns about the longevity of perpetual licenses and the company’s approach to product support. The change could also influence user trust and encourage migration to alternative office suites like LibreOffice or OnlyOffice.

Background
Microsoft launched Office 2019 and 2021 as one-time purchase products, marketed as permanent licenses. Support for Office 2019 ended in October 2023, while Office 2021 is scheduled to end in October 2026. The license validation process relies on a digital certificate that expires on July 13, 2026, affecting older versions that cannot be updated to include the renewed certificate. This is part of broader efforts to shift users toward Microsoft 365 subscriptions, which are continuously updated and supported.
“Apps that are updated to the minimum required versions already include the renewed certificate and continue to function normally. Apps on older versions enter reduced functionality mode after the certificate expires.”
— Microsoft support documentation
“Microsoft is using this expiration as a deadline that retires older versions of Office, rather than renewing the certificate. This is a deliberate choice.”
— JimmyTech, IT consultancy
“The user response to this change has been largely negative, with many users feeling betrayed by the company’s handling of perpetual licenses.”

Key Questions
Will Office 2019 and 2021 for Mac and iOS stop working entirely after July 13, 2026?
No, they will enter a ‘reduced functionality mode’ where files can only be viewed, not edited or saved. Full offline features will be unavailable without updates or upgrades.
Can I update Office 2019 to avoid this change?
No, Office 2019 has no update path to include the renewed license validation certificate, so it cannot be prevented from entering reduced functionality mode.
What options do I have if I want to continue using Office offline after July 2026?
You can upgrade to Office 2021 or Microsoft 365, switch to free web-based Office apps, or purchase a new perpetual license for Office 2024 or later.
Why is Microsoft making this change now?
The change is driven by the expiration of a license validation certificate used for offline activation, which cannot be renewed for older Office versions. It aligns with Microsoft’s shift toward subscription-based services.
