Urgent warning as Microsoft ends support for older Office versions
A critical update for Office users is looming. Microsoft has announced that support and security updates for older Office versions — including Office 2016 and Office 2019 — will end, with no further bug fixes or technical support after a designated deadline. The move affects several core Office applications, and users who fail to upgrade may face escalating security risks, reduced productivity, and compliance concerns.
Microsoft’s notice emphasizes that continuing to use software after the end of support can leave devices vulnerable to security threats. The company also stresses that now is the time to migrate all remaining devices running Office 2016 or Office 2019 to a supported version. The goal is to minimize exposure to exploits and ensure continued access to security patches and technical help when issues arise.
Which apps are affected?
The switch affects a broad set of Office apps and related services often used in business environments. Core programs such as Word, Excel, Outlook and PowerPoint are included, alongside other tools like Access, Publisher, and the Skype for Business ecosystem. While not every user relies on every app, a new update cycle means organizations should audit their software stack to align with supported versions.
Why updating now matters
End-of-support milestones come with several practical consequences. Without ongoing security updates, devices can become more susceptible to malware, phishing, and zero-day exploits. In addition, older software may miss compatibility updates for newer hardware or cloud services, which can lead to productivity losses or data handling issues.
Microsoft’s guidance is clear: upgrade sooner rather than later. For businesses, this can involve deploying the latest Office suite or moving users to a cloud-based subscription model with Microsoft 365. For individuals, updating to a supported standalone or subscription version helps maintain a secure, functional environment for daily tasks such as document editing, email, scheduling, and collaboration.
Practical steps to take now
1) Inventory your devices: List all machines still running Office 2016 or 2019 and identify those connected to critical workflows.
2) Plan the upgrade: Decide between upgrading to the latest perpetual version or migrating to Microsoft 365, weighing factors like cost, IT support, and remote work needs.
3) Test compatibility: Before a full rollout, test essential documents and add-ins to ensure smooth operation post-upgrade.
4) Roll out in stages: Start with high-priority teams, monitor performance, and address issues before broad deployment.
5) Update security practices: Reinforce cyber hygiene with updated antivirus tools, strong authentication, and regular backup routines as part of the migration.
What to expect from Microsoft
Microsoft has historically provided security fixes, bug fixes, and technical support for actively supported products. When support ends, users often lose access to critical patches, leaving gaps in protection and performance. Microsoft’s own statements frame the end-of-support period as an opportunity to migrate to supported products that receive ongoing updates and better integration with modern security features.
For organizations, the transition also offers a chance to modernize workflows—taking advantage of cloud features, real-time collaboration, and improved compliance controls. If you encounter issues during migration, contact your IT department or Microsoft support channels to ensure a smooth transition with minimal disruption.
Bottom line
As Microsoft ends support for Office 2016 and Office 2019, the imperative is clear: upgrade now to protect devices, maintain productivity, and stay compliant. Whether you manage a large corporate network or a smaller team, a proactive upgrade plan will reduce risk and keep your Office tools aligned with current security standards.
