If your organisation is still relying on Office 2016 or Office 2019, it’s time to start planning your next steps. As of 14 October 2025, Microsoft will officially end support for these products, including standalone applications like Word, Excel, PowerPoint, and Outlook. This change marks a critical juncture for businesses, and proactive planning is essential to avoid disruptions and maintain productivity.

What Does End of Support Mean?

When Microsoft ends support for a product, it no longer provides:

  • Security Updates: Without updates, your systems are more vulnerable to cyber threats.
  • Bug Fixes: Any issues or glitches will remain unresolved.
  • Technical Support: Microsoft will no longer assist with troubleshooting or usage queries.

For businesses, continuing to use unsupported software can result in compliance issues, productivity losses, and an increased risk of security breaches.

Products Impacted

The end-of-support announcement affects:

  • Office Suites: Office 2016 and Office 2019
  • Standalone Applications: Access, Excel, OneNote, Outlook, PowerPoint, Project, Publisher, Skype for Business, Visio, Word (2016 and 2019 versions)
  • Productivity Servers: Exchange Server 2016, Exchange Server 2019, Skype for Business Server 2015, Skype for Business Server 2019

Your Options Moving Forward

To ensure your business remains secure, compliant, and productive, Microsoft recommends two primary upgrade paths:

1. Transition to Microsoft 365 E3

Microsoft 365 E3 is a cloud-based solution that offers:

  • Always Up-to-Date Software: Access the latest versions of familiar Office applications.
  • Enhanced Security: Built-in tools to protect your data and devices.
  • Intelligent Services: Utilise cloud-based applications like Exchange Online, SharePoint Online, and Teams.
  • Generative AI Integration: With Microsoft 365 Copilot (available as an add-on), you can supercharge your productivity by incorporating AI into your workflows.

2. Upgrade to Office LTSC 2024

For organisations with devices that can’t connect to the cloud, Office Long-Term Servicing Channel (LTSC) 2024 offers a perpetual licence with:

  • Basic Updates: Security and bug fixes for disconnected environments.
  • Limited Features: Note that LTSC versions don’t include cloud-based features or compatibility with Microsoft 365 Copilot.

Next Steps for Your Business

To ensure a smooth transition, we recommend:

  • Assess Your Current Setup: Identify which devices and users are still reliant on Office 2016 or 2019.
  • Plan Your Migration: Evaluate whether Microsoft 365 E3 or Office LTSC 2024 is the best fit for your organisation’s needs. Consider factors like internet connectivity, compliance requirements, and long-term scalability.
  • Engage a Trusted Partner: Transitioning to new software can be complex. Partnering with a managed service provider like Vissensa ensures your migration is seamless and tailored to your specific requirements.

Why Act Now?

Delaying your upgrade can lead to:

  • Increased Security Risks: Unsupported software is a prime target for cyberattacks.
  • Compliance Violations: Many industries mandate the use of supported software to meet regulatory standards.
  • Operational Disruptions: Without access to technical support, even minor issues can escalate into major setbacks.
