Microsoft is disabling Office 2019 for Mac on July 13, 2026
Summary:
Starting July 13, 2026, Office 2019, older versions of Office 2021, and older versions of Microsoft 365 apps on Mac and iOS will refuse to let you edit or save files.
Microsoft 365 subscribers and Office 2021 owners can fix this with a free Office update (and a macOS update first, if running Big Sur or earlier).
Office 2019 owners cannot. Microsoft will not release an update that resolves it, even for people who paid full price for a one-time purchase license.
If you bought Microsoft Office 2019 for Mac outright, I have bad news. On July 13, 2026, Microsoft is going to disable the editing features of the apps you paid for. You will still be able to open documents and print them, but you will not be able to make changes or create new ones. This is a shabby thing for a company to do. End of support is one thing. Disabling software people purchased is another.
What is actually changing on July 13, 2026?
According to Microsoft's support page, Office apps (Word, Excel, PowerPoint, Outlook, and OneNote) on Mac, iPhone, and iPad will enter what Microsoft calls "reduced functionality mode." In that mode, you can open, view, and print files, but you cannot edit, save changes, or create new documents. Windows and Android versions are not affected.
Why is Microsoft doing this?
Microsoft says a certificate they use to validate your Office license is expiring. When it does, the apps cannot confirm that you have a valid license, so they stop letting you make changes. But certificates can get renewed. The fact that Microsoft is using this expiration as a deadline that retires older versions of Office, rather than quietly renewing the certificate, is a choice. In October 2023, when Microsoft ended support for Office 2019 for Mac, they explicitly told customers: "Rest assured that all your Office 2019 apps will continue to function." This sounds to me like they are now breaking that promise.
Does this affect me?
Open any Office app like Word, then choose Word > About Word from the menu bar at the top of the screen. Two pieces of information matter:
The version number. If it is 16.83 or higher, you are set and the rest of this article is not urgent for you. If it is 16.82 or lower, you need to take action before July 13.
The License line. It will say something like Office 365 Subscription, Retail License 2021, or Retail License 2019. This tells you which option in the table below applies to you.
Match your license type and your macOS version against the table.
What should you do?
Find your license type under Word > About Word. Match it and your macOS version to see what to do before July 13, 2026.
| License type | macOS version | What you need to do |
|---|---|---|
| Office 365 Subscription | macOS 12 or later | Make sure Office is version 16.83 or higher through Help > Check for Updates. |
| Retail License 2021 | macOS 12 or later | Make sure Office is version 16.83 or higher through Help > Check for Updates. Note: Office 2021 itself reaches end of support on October 13, 2026. |
| Office 365 Subscription or Retail License 2021 | macOS 11 or earlier | Update macOS to Monterey (12) or later first, then update Office. If your Mac cannot run macOS 12, it may be time for a Mac upgrade. |
| Retail License 2019 | Any version | Microsoft will not release a fix. Subscribe to Microsoft 365, buy Office 2024, or switch to a free alternative like Pages or Google Docs. |
If you do not see "Check for Updates" under the Help menu, you likely installed Office from the Mac App Store. Open the App Store, click your name in the lower-left corner, and look for updates there.
What about Office on my iPhone or iPad?
The same change applies to Office apps on iPhone and iPad. In practice this is rarely an issue because iPhones and iPads update their apps automatically much more reliably than Macs do. But it is worth a quick check. Open Word on your iPhone or iPad, tap your profile picture in the upper left, and look for an About or Version option. If you cannot easily find it, the simpler answer is to open the App Store, tap your profile picture, and pull down to refresh. If Word, Excel, or PowerPoint are listed as available updates, install them.
Common mistakes to avoid
Mistake 1: Falling for unofficial "fix it" downloads. This is exactly the kind of situation where scammers create fake "Office license repair" tools. Microsoft has also started sending real emails to affected customers, which makes the scam risk worse because everyone is now primed to expect Office-related messages. Do not click links in any "Office update required" email, even ones that look legitimate. Instead, go directly to office.com or microsoft.com in your browser.
Mistake 2: Buying Office 2024 as a one-time purchase without thinking about what comes next. Every five years or so, Microsoft retires the one-time purchase version of Office for Mac. If you spend $149.99 on Office Home 2024 today (or $249.99 for Home & Business 2024, which adds Outlook), expect this to happen again around 2029 or 2030. The math still favors the one-time purchase over a Microsoft 365 subscription if all you want is the apps, but the real appeal of the subscription is that you never have to worry about this kind of disruption again. If you do not specifically need Microsoft Office, consider a free alternative like Pages, Google Docs, or LibreOffice instead.
Mistake 3: Thinking that this will cause you to lose your files. It will not. Your files will still be there and you can open them. You just will not be able to edit them until you upgrade or switch to a free alternative app. Microsoft Office is the tool. It does not actually contain your documents, just as a pen does not contain your letters.
Mistake 4: Not coordinating with other family members. Microsoft 365 Family is $129.99 per year and can be shared with up to five other people. Before you buy your own subscription, ask around. If an adult child, parent, or sibling already has Family, they can add you at no extra cost to either of you. If they have Microsoft 365 Personal ($99.99 per year), it costs them only $30 more per year to upgrade to Family and add you.
Mistake 5: Waiting because you might get a new Mac soon. A copy of Office is tied to you, not to your computer. If you buy a Microsoft 365 subscription or Office 2024 today and then get a new Mac next year, you can install it on the new Mac at no extra cost. Do not put off solving this just because a new computer might be in your future.
Key Takeaways
Check your Office version under Word > About Word. If it is 16.83 or higher you are set. If it is 16.82 or lower, take action before July or your Office apps will stop letting you edit files.
If you have Microsoft 365 or Office 2021, update macOS to Monterey (12) or later and update Office before July 13, 2026.
If you have Office 2019, plan now: a Microsoft 365 subscription, an Office 2024 purchase, or a free alternative like Pages or Google Docs.
Have your solution in place by July 13 so you can keep working without interruption.
