🚨 Office 365 ProPlus Support Ends for Some Windows Versions

What You Need to Know

---

There’s a simple rule in IT: If you ignore lifecycle dates, sooner or later, they’ll catch up with you. And today is one of those moments.

As of January 14, 2020, Microsoft officially ends support for Office 365 ProPlus on several older Windows versions. Why? To ensure customers get the best experience from both Office and Windows—and because running modern cloud services on outdated systems is like installing a Ferrari engine in a horse-drawn carriage.

Time to pay attention.

💡 What’s Actually Changing?

---

Office 365 ProPlus (now called Microsoft 365 Apps for Enterprise) is Microsoft’s cloud-connected productivity suite. It delivers:

• Always up-to-date Office apps
• Integrated Microsoft 365 services
• Security updates and cloud innovations
• And seamless management via tools like Endpoint Configuration Manager

But here’s the catch: To keep pace, your underlying Windows OS must be current.

Microsoft recently tightened its system requirements:

🚫 From now on, Office 365 ProPlus will NOT be supported on:

• All Windows 10 LTSC/LTSB versions
• Windows Server 2012 / 2012 R2
• Windows 7 (even with Extended Security Updates!)

✅ Still supported:

• Windows 8.1 (until January 2023)
• Windows Server 2016 (until October 2025)

If you’re still running older systems, it’s upgrade time—or you’re heading straight into unsupported territory.

⚙️ Why This Matters

---

I get it. Many businesses run Windows 7 or Server 2012 in production because “it works” or because upgrades feel risky. But Microsoft is clear: running modern, cloud-connected Office apps on unsupported operating systems is:

• A security risk
• A performance bottleneck
• And, frankly, an IT management nightmare

Modern features like:

• Seamless OneDrive integration
• Microsoft Search
• AI-powered Office experiences
• Microsoft Teams
• And fast, reliable patching

…simply aren’t designed for outdated Windows platforms.

And trust me, your cybersecurity team will thank you when that ransomware attack doesn’t exploit your decade-old OS.

🖥️ What About Remote Desktop & VDI Scenarios?

---

Now, for the nerds among us (myself included), you might ask:

“But Uwe, what about Remote Desktop Services (RDS) and Virtual Desktop Infrastructure (VDI)?”

Good question! Remote environments—especially in Microsoft Azure—remain a key scenario for Office 365 ProPlus.

Microsoft is committed to:

• Supporting Office 365 Apps on Windows Virtual Desktop (WVD)
• Enabling key features like Microsoft Edge, Store for Business, and Cortana
• Keeping deployment models like Monthly Update Channels and Semi-Annual Enterprise Channels aligned

So yes—Office 365 Apps in a virtual environment are alive and well. Just ensure your host OS meets the latest support standards.

🔥 Still on Windows 7? Here’s What Happens Next

---

If you’re still clinging to Windows 7 (I know some of you are!), here’s your reality:

• Version 2002 of Office 365 ProPlus is your last stop.
• It will continue receiving security updates only until January 2023.
• No feature updates. No new functionality.

Try installing a newer version, like 2005?
You’ll get a friendly but firm error message.

To manage version 2002:

• Continue using your existing deployment tools (Office Deployment Tool, Endpoint Configuration Manager)
• Stay on your current update channel
• Accept that you’re in extended maintenance mode

If you’re waiting for a sign to upgrade… this is it. ⏰

---

📦 What Happens After the Upgrade?

---

Once your devices move to Windows 10 (preferably 21H2+), the world opens up:

• Automatic updates to the latest Office builds
• Access to all missed feature updates
• Modern security and productivity enhancements
• Smooth management with Microsoft 365 Admin Center and Endpoint Manager

Because remember:
Office 365 Apps use cumulative updates. When you upgrade, you get everything you’ve missed in one streamlined jump.

---

🛠️ Why This Is Actually a Good Thing

---

Let’s be real: Change is hard. But staying stuck on legacy operating systems in 2020 (or beyond) holds you back from:

• AI-enhanced productivity
• Seamless cloud integrations
• Next-level security frameworks

In the Microsoft Cloud world, modern apps depend on modern OS foundations.

Staying current is no longer “nice to have”—it’s mission-critical.

📋 TL;DR – What You Need to Know

---

❌ Unsupported for Office 365 Apps	✅ Supported for Office 365 Apps
Windows 7 (even with ESU)	Windows 8.1 (until Jan 2023)
Windows Server 2012 / R2	Windows Server 2016 (until 2025)
Windows 10 LTSC / LTSB	Windows 10 SAC (latest builds)

💡 Pro tip: If you’re planning your next upgrade, avoid LTSC unless your use case demands it. LTSC versions are designed for specialized, stable environments—not general productivity workloads.

🤓 Final Thoughts from Mr. Microsoft

---

I get it. Licensing is complex. System requirements feel like the fine print of the cloud world. But ignoring lifecycle milestones in Microsoft 365 is like ignoring your car’s oil light—it’ll bite you sooner or later.

Here’s my advice:

• Upgrade to Windows 10 (or Windows 11)
• Move Office to the latest update channels
• Embrace modern management with Microsoft Endpoint Manager

Your users will thank you. Your security team will love you. And your CIO will finally stop asking why Teams crashes on Windows 7.

Stay clever. Stay current.
Your Mr. Microsoft,
Uwe Zabel
