Microsoft has determined that it will essentially "block" the main functions of the independent version of Office 2019 on Mac, iPad and iPhone starting from July 13, 2026. Users have almost no way to prevent this change and can only choose to pay again to purchase a new version of the license or switch to the Microsoft 365 subscription service. This means that Office 2019, which was originally purchased as a one-time purchase, will be forced into a "slimming mode" that is almost unavailable after the support period ends.

According to reports, Microsoft will officially end technical support for the Mac version of Office 2019 as early as October 2025, but the software itself will continue to work normally at that time. However, after the implementation of the New Deal, no matter how new the user’s hardware is or which version of the Apple operating system they are running, the core functions of Office 2019 will be significantly weakened.

Microsoft plans to disable most Microsoft Office features running on macOS 11 Big Sur starting on July 13, 2026, while locking Office 2019 on all platforms into read-only mode. This adjustment also covers the mobile side. Office applications running iPadOS 16 and iOS 16 or earlier systems will be "deprecated" and users will no longer be able to edit documents normally through existing apps.

In so-called "restricted mode," users can still open and view their Office files and print. However, users will not be able to make any edits to the document, save changes, or create new files, and the office suite will completely degrade into a read-only browsing tool. The report described this model as not so much a "limited function" but a direct signal from Microsoft to users to "please pay again."

For users who are already using Microsoft 365 or Office 2021, if their devices are still stuck on macOS 11 or earlier and want to continue using Office normally, they must upgrade the system to macOS 12 Monterey or later. On Mac, users need to go into Settings, select General, then click Software Update when a system update is available and follow the prompts to complete the upgrade.

On iPhone and iPad, Microsoft also requires users to upgrade the operating system to maintain the full functionality of Office. The steps are to open the "Settings" application, click "General", and if a new system version is available, download and install it in "Software Update" to continue using the latest version of Office applications.

Microsoft has also offered a compromise for older Mac users who are unable to upgrade to macOS 12 or newer due to hardware limitations. The report pointed out that such users can consider purchasing a Microsoft 365 subscription, access the online version of Office services through the browser, and continue to edit and save documents. Although this method is not as convenient as local application in terms of long-term use convenience, it can at least ensure the operability of the file.

It should be noted that Microsoft’s current support policy for one-time buyout versions also determines users’ choice space. The company has made it clear that it will only offer a 5-year support cycle for Office versions purchased as a one-time purchase. This means that support for Office 2021 will end at the end of 2026, while Office 2024, which has just been launched, will receive official support until 2029 according to the rules.

The report mentioned that if users plan to continue to use the "one-time buyout" licensing model, choosing Office 2024 will be a more cost-effective approach. Under Microsoft's five-year support window, Office 2024 can provide longer security updates and compatibility guarantees than Office 2021. In addition, Apple's latest system, macOS 14 Sonoma, has become the minimum system requirement for Office 2024, and users on this platform themselves are not affected by this round of adjustments.

What’s even more controversial is that for Mac users who are still using Office 2019, there is almost no room for exemptions from this “blocking” measure. The report quoted Microsoft support documents as saying that regardless of whether users have upgraded to the latest macOS 26 or are still using older versions of the system, Office 2019 will be "uniformly liquidated" at the functional level. This approach is in sharp contrast to the fact that many online channels are still actively selling Office 2019 licenses, and it has also caused users to question the concept of "lifetime licensing" of software.

In this case, Office 2019 users are effectively forced to choose between several paths: either purchase a new generation of one-time licensed products such as Office 2021 or Office 2024, or move to a Microsoft 365 subscription service. Apple continues to provide free iWork suites, and third-party office software such as open source LibreOffice has also become an alternative for some users to avoid Microsoft's ecological lock-in.

The report pointed out that for users who prefer working in the cloud, Microsoft itself also provides free-level web-based Word and Excel services. Users can access and perform basic editing operations through the browser, and only need to log in with a Microsoft account. However, for a large number of professional users who are accustomed to local installation and rely on complex functions and macro scripts, these solutions may not be able to completely replace the traditional desktop version of Office.

Against the background of the industry's overall migration to the subscription model, Microsoft's "hard cutoff" strategy for Office 2019 once again highlights the growing contradiction between users buying out the software and continuing to use it. For individual users and small and medium-sized enterprises, the original expectation of "buy once and use them for a long time" is being continuously compressed, while the long-term cost of maintaining the availability of productivity tools continues to rise.
