If you’re among the millions still running trusty old versions of Microsoft Office—perhaps rocking a PowerPoint presentation from the Stone Age (2016) or toiling in Excel as recently as 2019—there’s an existential storm brewing on your digital horizon. In a move that’s equal parts business-as-usual and harbinger-of-chaos, Microsoft has announced a hard stop for support on Office 2016 and Office 2019. Come October 14, 2025, these venerable suites are officially being put out to pasture. What does that mean? Well, grab your security blanket—or at least your GDPR compliance cheat sheet—because the party’s almost over.
If you’ve been around tech long enough, you’ll know the lifecycle story: Microsoft launches a shiny new product, promising the world. Years pass, users get comfortable—maybe too comfortable. Then, with a polite but pointed announcement, Microsoft pulls the support rug out from under those clinging to yesterday’s software. It’s almost tradition now, the tech world’s equivalent of pushing baby birds out of the nest.
For Office 2016 and 2019, the wings get clipped in October 2025. That’s when security updates and technical support vanish, leaving every spreadsheet, budget, and marketing mail merge just a little more vulnerable. Even more damning: Office 2019 hasn’t been feeling the love from mainstream support since October 2023, and Office 2016 has been on extended support life support since 2020. If these suites were people, they’d be the retirees at the end of a company banquet, sipping lukewarm coffee and reminiscing about server rooms gone by.
Microsoft’s warning isn’t academic. Once support ends, updates—especially those sweet, life-saving security patches—cease. You’re left exposed. And for companies, the risks multiply: data breaches, compliance violations (think GDPR or HIPAA nightmares), and system quirks that no IT admin can fix, all become pressing realities. Office suites are often the backbone of daily business operations. Run unsupported, and suddenly you have a rickety backbone prone to spasms and spectacular, costly collapses.
Let’s be honest: The subscription model works well for Microsoft, and if you like your technology invisible and seamless, it works for you, too. With Microsoft 365, you avoid those “update or else” moments. Your software quietly evolves, out of sight and usually out of mind. You get compatibility with new file formats, enhanced security, and the warm fuzzies of knowing Microsoft’s cyber defense team is working for you in the background.
Enter Office 2024. Released as a standalone, non-subscription offering for small businesses and individuals, Office 2024 packs Word, Excel, PowerPoint, OneNote, and Outlook for both Windows and macOS. It’s as close to old-school as you’ll get without breaking out floppy disks.
There’s also Office LTSC 2024 (Long Term Servicing Channel), designed for very special cases: think air-gapped machines in a secure basement, point-of-sale systems, or anything running where the internet is a forbidden luxury. LTSC offers four years of support—until October 2029—making it the ideal choice for environments where updating to the latest feature isn’t just annoying; it’s potentially catastrophic.
Unsupported software is catnip for cybercriminals. Every known vulnerability is a potential entry point, and since attackers know you’re never getting another patch, they’re free to scan the internet for unprotected installations. Once inside, malware can spread quickly—ransomware being the current flavor of the decade. If your company has ever received a chilling “your files are encrypted, pay in Bitcoin” message, you’ll know exactly how this plays out.
Then there’s the compliance nightmare. Regulations aren’t getting lighter, and unsupported, unpatched software is the very definition of “non-compliant.” You risk not just the wrath of regulators but also the trust of your customers and clients. One costly data leak can undo decades of hard-won reputation.
Let’s not forget ergonomics. Newer Office versions come with accessibility improvements, AI features (that Copilot again!), collaboration tools, and integrations with services everyone’s using. Stick with the old versions long enough, and you’ll feel the technological equivalent of a dial-up modem in a fiber-optic world. Not only do you risk falling behind, but you may not even realize what you’re missing.
Step one is a thorough inventory. Find every copy of Office in your environment. Did that accounting workstation in the basement get overlooked last time? Are there lingering copies on old laptops, or a neglected business unit still running Office 2016? This is also an excuse to audit your licenses and see where you’re legally and practically exposed.
Step two: prepare your people. Change management isn’t just jargon—it’s critical. You’ll need to communicate why upgrades matter, what’s changing, and when it will happen. Expect pushback—some folks love the ribbon as it was in 2016! Training sessions, cheat sheets, and phased rollouts help reduce the pain.
Step three: test before you leap. Especially in larger or complex IT environments, test-drive new versions with a pilot group. Check that critical macros, plugins, and processes still work. Compatibility testing can prevent major headaches when you finally flip the organizational switch.
For businesses looking to automate routine processes, boost efficiency, or simply keep up with the Joneses, Copilot might be the justification for an upgrade all by itself. That’s assuming, of course, you’re not running on an ancient version with zero hope of AI integration.
Still, for nonprofits, small businesses, and the chronically cash-strapped, every dollar counts. Microsoft offers discounts for certain groups, and the presence of Office 2024 and LTSC means there’s still some flexibility. Hybrid approaches—mixing subscription and one-time licenses based on role and risk—are also increasingly common.
Ultimately, the right path is less about what’s easiest, and more about what’s safest and most sustainable. Whether you opt for Microsoft 365, kick the can down the road with Office 2024, or install LTSC on that one aging workstation, the key is intentionality—not inertia.
No one loves mandatory software upgrades, but the alternative is a slow fade into digital irrelevance—peppered with a higher risk of data breaches, non-compliance fines, and panicked weekend calls to the IT department. Invest time and resources now, and you’ll be rewarded not just with fewer headaches, but with that golden halo of digital resilience.
And if, by chance, you do decide to ride Office 2016 or 2019 into the unsupported sunset, just remember: The real end of support isn’t when Microsoft says, but when you discover for yourself exactly what “unprotected” feels like. Don’t say you weren’t warned.

The Great Office Cutoff: A Brief History of Deprecation
If you’ve been around tech long enough, you’ll know the lifecycle story: Microsoft launches a shiny new product, promising the world. Years pass, users get comfortable—maybe too comfortable. Then, with a polite but pointed announcement, Microsoft pulls the support rug out from under those clinging to yesterday’s software. It’s almost tradition now, the tech world’s equivalent of pushing baby birds out of the nest.For Office 2016 and 2019, the wings get clipped in October 2025.

If these suites were people, they’d be the retirees at the end of a company banquet, sipping lukewarm coffee and reminiscing about server rooms gone by.
What’s Really at Stake? Security Gaps and Compliance Quicksand
If you’re thinking, “Big deal—the software will keep running,” you’d be right. It will. But imagine driving a beloved car after the manufacturer stops making brake pads. Sure, it moves, but would you trust it for the school run? Similarly, unsupported software makes your machine a sitting duck for hackers. And in the interconnected world of 2025’s digital workplace, that’s like inviting cyber-criminals to Thanksgiving dinner—just don’t be surprised when they take the silverware.Microsoft’s warning isn’t academic. Once support ends, updates—especially those sweet, life-saving security patches—cease. You’re left exposed. And for companies, the risks multiply: data breaches, compliance violations (think GDPR or HIPAA nightmares), and system quirks that no IT admin can fix, all become pressing realities. Office suites are often the backbone of daily business operations. Run unsupported, and suddenly you have a rickety backbone prone to spasms and spectacular, costly collapses.
Microsoft 365 and Office 365: The Subscription Solution
Microsoft’s answer isn’t subtle. They’d very much like you to subscribe to Microsoft 365 or Office 365, thank you. These services offer the latest versions of Word, Excel, PowerPoint, and their ilk—on desktop, mobile, and online—all bundled under the auspices of the Modern Lifecycle Policy. This means continuous support, regular updates, and, crucially, a steady drip of new features and integrations (hello Copilot, Microsoft’s AI sidekick).Let’s be honest: The subscription model works well for Microsoft, and if you like your technology invisible and seamless, it works for you, too. With Microsoft 365, you avoid those “update or else” moments. Your software quietly evolves, out of sight and usually out of mind. You get compatibility with new file formats, enhanced security, and the warm fuzzies of knowing Microsoft’s cyber defense team is working for you in the background.
The Alternatives: One-Time Licenses for the Stubborn and Security-Minded
But what if subscriptions aren’t your cup of chamomile tea? You’re not alone. Some organizations—especially those paranoid about sending data to the cloud or navigating recurring billing cycles—want the old model: buy it once, keep it forever (or at least until Microsoft knocks on your door again).Enter Office 2024. Released as a standalone, non-subscription offering for small businesses and individuals, Office 2024 packs Word, Excel, PowerPoint, OneNote, and Outlook for both Windows and macOS. It’s as close to old-school as you’ll get without breaking out floppy disks.
There’s also Office LTSC 2024 (Long Term Servicing Channel), designed for very special cases: think air-gapped machines in a secure basement, point-of-sale systems, or anything running where the internet is a forbidden luxury. LTSC offers four years of support—until October 2029—making it the ideal choice for environments where updating to the latest feature isn’t just annoying; it’s potentially catastrophic.
What If You Do… Nothing? The Risks Pile Up
Maybe you’re a gambling type. You’ll stick with your trusty edition until it gives up the ghost, and you’ll accept the risk. After all, how big a target could your Midwest widget factory or small-town insurance office be? Sadly, that’s what the hackers are banking on.Unsupported software is catnip for cybercriminals. Every known vulnerability is a potential entry point, and since attackers know you’re never getting another patch, they’re free to scan the internet for unprotected installations. Once inside, malware can spread quickly—ransomware being the current flavor of the decade. If your company has ever received a chilling “your files are encrypted, pay in Bitcoin” message, you’ll know exactly how this plays out.
Then there’s the compliance nightmare. Regulations aren’t getting lighter, and unsupported, unpatched software is the very definition of “non-compliant.” You risk not just the wrath of regulators but also the trust of your customers and clients. One costly data leak can undo decades of hard-won reputation.
The Subtle Risks: Productivity, Compatibility, and the Dreaded “It Just Doesn’t Work”
Security and compliance hog the spotlight, but they’re far from the only headaches. Software compatibility is a slow-burning fuse. New Windows versions and Office documents may be incompatible with ancient versions. Soon, that file your client sent won’t open, or the macro your accountant depends on starts throwing cryptic errors.Let’s not forget ergonomics. Newer Office versions come with accessibility improvements, AI features (that Copilot again!), collaboration tools, and integrations with services everyone’s using. Stick with the old versions long enough, and you’ll feel the technological equivalent of a dial-up modem in a fiber-optic world. Not only do you risk falling behind, but you may not even realize what you’re missing.
Deciding When—and How—to Upgrade
So you’re convinced: running unsupported software is like skydiving with a questionable parachute. But what now? For organizations, this is where procurement, IT, and user experience intersect—and sometimes clash.Step one is a thorough inventory. Find every copy of Office in your environment. Did that accounting workstation in the basement get overlooked last time? Are there lingering copies on old laptops, or a neglected business unit still running Office 2016? This is also an excuse to audit your licenses and see where you’re legally and practically exposed.
Step two: prepare your people. Change management isn’t just jargon—it’s critical. You’ll need to communicate why upgrades matter, what’s changing, and when it will happen. Expect pushback—some folks love the ribbon as it was in 2016! Training sessions, cheat sheets, and phased rollouts help reduce the pain.
Step three: test before you leap. Especially in larger or complex IT environments, test-drive new versions with a pilot group. Check that critical macros, plugins, and processes still work. Compatibility testing can prevent major headaches when you finally flip the organizational switch.
Unique Use Cases: Edge Cases and Special Needs
Despite Microsoft’s push toward the cloud, whole industries run on edge cases. Consider:- Healthcare: Air-gapped machines running critical equipment, where internet connectivity is forbidden.
- Manufacturing: Factory floors running custom automation software tied to specific Office macros.
- Government and Defense: Sensitive environments prioritizing control over update frequency.
The Copilot Factor: Why AI Is the Secret Sauce in Newer Versions
One of the under-appreciated benefits of keeping current is access to Microsoft 365 Copilot, an all-singing, all-dancing AI assistant integrated into the new Office suite. Copilot isn’t just a smarter spellchecker; think natural language queries in Excel, AI-generated PowerPoints, and Word documents that almost write themselves.For businesses looking to automate routine processes, boost efficiency, or simply keep up with the Joneses, Copilot might be the justification for an upgrade all by itself. That’s assuming, of course, you’re not running on an ancient version with zero hope of AI integration.
Is Cost a Barrier or a Convenient Excuse?
There’s no getting around it—upgrading costs money. Microsoft 365 subscriptions are a line item on every IT budget. But consider the alternative: The average cost of a single data breach, factoring in fines, lost productivity, and reputational harm, dwarfs the collective price of staying up to date.Still, for nonprofits, small businesses, and the chronically cash-strapped, every dollar counts. Microsoft offers discounts for certain groups, and the presence of Office 2024 and LTSC means there’s still some flexibility. Hybrid approaches—mixing subscription and one-time licenses based on role and risk—are also increasingly common.
A Wake-Up Call, Not a Doomsday Prediction
It’s tempting to read Microsoft’s latest warning as another attempt to drive subscription numbers. And yes, there’s a profit motive. But the security risks are real, and the compliance picture is more daunting with each passing year. More than anything, the end of support should be a wake-up call—for IT pros grasping at old habits, for small business owners nervous about change, and for anyone still treating “security through obscurity” as a strategy.Ultimately, the right path is less about what’s easiest, and more about what’s safest and most sustainable. Whether you opt for Microsoft 365, kick the can down the road with Office 2024, or install LTSC on that one aging workstation, the key is intentionality—not inertia.
The Road Ahead: Prepare, Plan, Upgrade
The sunset of Office 2016 and 2019 isn’t an asteroid strike; it’s a forecast you can plan for. Take stock now. Talk to your stakeholders. See the writing on the (virtual) wall, and plot a course forward long before October 2025 sneaks up.No one loves mandatory software upgrades, but the alternative is a slow fade into digital irrelevance—peppered with a higher risk of data breaches, non-compliance fines, and panicked weekend calls to the IT department. Invest time and resources now, and you’ll be rewarded not just with fewer headaches, but with that golden halo of digital resilience.
And if, by chance, you do decide to ride Office 2016 or 2019 into the unsupported sunset, just remember: The real end of support isn’t when Microsoft says, but when you discover for yourself exactly what “unprotected” feels like. Don’t say you weren’t warned.
