The End of Support for Microsoft Office 2016 and Prior: What You Need to Know and How to Prepare

October 14, 2025, marks a critical date for many organizations: Microsoft Office 2016 and earlier versions will officially reach End of Support (EOS). While these products may continue to function, they will no longer receive feature updates or technical support—and only limited security patches, if any. 

This shift could pose serious challenges for businesses still relying on these tools. 

Why This Matters

Unsupported software introduces risk. Here’s what’s at stake: 

• Security vulnerabilities: Without updates, these products become more susceptible to cyber threats and breaches. 
• Compliance challenges: Unsupported systems can jeopardize regulatory compliance, particularly in industries with strict data governance. 
• Operational inefficiencies: As other technologies evolve, older Office products may struggle with compatibility, limiting productivity and collaboration. 
• Licensing pitfalls: Continuing to run out-of-date software could create licensing and audit issues. 

Don’t Wait—The Clock Is Ticking 

With the EOS deadline fast approaching, now is the time to act. Proactive planning today can help you reduce risk, streamline operations, and position your business for long-term success.
