If your business is still relying on Microsoft Office 2016 or Office 2019, it’s time to start planning for an upgrade.
On October 14, 2025, Microsoft will officially end all support for both versions—meaning security updates, bug fixes, and technical assistance will no longer be available for both. While these legacy tools have served many organizations well over the years, continuing to use them beyond their support window introduces serious risks to your business.
Let’s explore what this means and why action is needed now.
Security Will Be Your Biggest Concern
Once Microsoft ends support, Office 2016 and 2019 will no longer receive security patches. Any newly discovered vulnerabilities in Word, Excel, Outlook, or other components will remain unpatched, leaving your systems and sensitive data at risk.
Cybercriminals are quick to exploit outdated software. Businesses that delay upgrading could become easy targets for:
• Phishing attacks through email vulnerabilities
• Ransomware embedded in Office documents
• Exploits using macros or embedded links
• Data leaks due to compromised Outlook clients
Legal and Compliance Risks
If your business operates in a regulated industry such as healthcare, legal, or finance, using unsupported software may put you out of compliance with security and privacy standards.
You could face:
• Auditing challenges
• Violation of industry-specific regulations
• Cyber insurance claim denials if a breach occurs on unsupported software
Compatibility Issues Will Multiply
As Microsoft and other software vendors continue releasing new tools and integrations, Office 2016 and 2019 will quickly fall behind. You may run into:
• File format errors when opening newer Office files
• Integration failures with Microsoft Teams, OneDrive, and SharePoint
• Limited functionality with newer email or collaboration systems
• Lack of technical support from Microsoft and third-party vendors
Delaying Could Cost More Later
Waiting until the last minute to replace Office 2016 or 2019 could result in:
• Unexpected upgrade expenses
• Disruption to employee workflows
• Lost productivity during emergency transitions
• Data compatibility problems during the switch
What You Can Do Now
Here’s how to prepare:
1. Take Inventory – Identify devices still using Office 2016 or 2019.
2. Review Licensing Options – Evaluate Microsoft 365 or Office 2021 as your next step.
3. Create a Rollout Plan – Schedule upgrades to minimize disruption.
4. Train Your Team – Ensure employees understand any new tools or interfaces.
Don’t Wait Until October
The October 14 deadline is fast approaching, and Microsoft will not be extending support. Upgrading now ensures your business stays secure, compliant, and productive.
