The 2026 deadline for SharePoint 2016 & 2019: What every business should know

Microsoft has officially announced that SharePoint 2016 and 2019 will reach end of life in July 2026. For businesses still running on these versions, the countdown has already begun. The decision to stay or migrate will directly impact security, compliance, and business continuity. This blog explores what the end of life means, why it matters, and how organizations can prepare for a seamless transition.

Understanding End of Life (EOL)

End of life (EOL) means that a product will no longer be supported by its vendor. Once SharePoint 2016 and 2019 reach this point, Microsoft will stop providing:

• Security Updates – Leaving systems increasingly vulnerable to cyber threats.
• Technical Support – No access to Microsoft’s troubleshooting or bug resolution.
• Feature Updates – No new enhancements, limiting modernization potential.
• License Purchases – While existing licenses remain valid, new ones cannot be purchased.

Why businesses need to act

Continuing unsupported platforms poses significant risks. Here’s why migration can’t be delayed:

1. Security Risks
Unsupported software becomes a target for cyberattacks. Without patches, vulnerabilities remain open, putting sensitive data at risk. Migrating to Microsoft 365 or a supported SharePoint version ensures consistent protection.

2. Compliance Requirements
Industries with strict data protection rules cannot afford compliance failures. Unsupported software makes audits and certifications harder, potentially leading to fines and legal issues.

3. Access to Modern Features
SharePoint Online within Microsoft 365 offers features not available in older versions, including integrations with Teams, Power Platform, AI-powered search, and advanced collaboration tools.

4. Enhanced User Experience
Modern platforms provide intuitive interfaces and improved navigation, helping employees work faster and collaborate more effectively.

5. Cost Efficiency
Sticking with outdated systems increases maintenance costs, downtime risks, and potential financial losses from breaches. Migration may require upfront investment but reduces long-term expenses.

Migration: The path forward

Migrating away from SharePoint 2016 and 2019 isn’t just about avoiding risks, it’s about preparing for the future. Benefits of migration include:

• Stronger security and compliance support.
• Access to modern features and AI-driven insights.
• Reduced costs are tied to maintenance and downtime.
• Continuous updates and future-ready capabilities.

What does migration mean for your business?

Migration goes beyond a technical upgrade. It enables organizations to strengthen collaboration and streamline efficiency, so following a structured approach becomes critical.

• Assessment: Audit existing SharePoint environments, data, and workflows.
• Planning: Create a migration roadmap with timelines, resources, and risk controls.
• Execution: Select the right migration model, whether a phased move to SharePoint Online or adoption of SharePoint Server Subscription Edition.
• Training: Prepare teams with guidance and training for smooth adoption.

Conclusion

The end of support for SharePoint 2016 and 2019 in 2026 is a critical milestone. Businesses that take proactive steps now will strengthen security, meet compliance standards, and improve employee collaboration. Migration is not just a safeguard; it’s a growth opportunity.
