What Is Happening?
Microsoft has confirmed that SharePoint Server 2016 and SharePoint Server 2019 will both reach their end of support on 14 July 2026. After this date, Microsoft will no longer provide security updates, bug fixes, or technical support for these on-premises versions.
Organisations still running these platforms face significant security and compliance risks. Without regular patches, known vulnerabilities will remain unaddressed, leaving your environment exposed to cyber threats.
Key Dates at a Glance
| Milestone | Date | Impact |
|---|---|---|
| SharePoint Server 2016 End of Support | 14 July 2026 | No security updates, patches or support |
| SharePoint Server 2019 End of Support | 14 July 2026 | No security updates, patches or support |
| Office Online Server End of Support | 31 December 2026 | No browser-based Office viewing/editing |
| SharePoint Server Subscription Edition | Available now | Perpetual on-premises option with updates |
| SharePoint Online (Microsoft 365) | Available now | Cloud-hosted, always up to date |
Why Does This Matter?
Running unsupported software carries real business risk:
Security vulnerabilities: Without patches, newly discovered exploits will go unresolved. Microsoft Threat Intelligence has documented state-sponsored actors targeting unpatched SharePoint Server instances.
Compliance exposure: Regulations such as GDPR, Cyber Essentials, and ISO 27001 typically require regularly patched software. Falling out of support can jeopardise certification.
No technical assistance: Microsoft Support will no longer troubleshoot issues or provide hotfixes after the end-of-support date.
Your Migration Options
1. Migrate to SharePoint Online (Microsoft 365)
Move to the cloud for automatic updates, built-in security, seamless integration with Teams and Copilot, and no on-premises infrastructure to manage. This is the recommended path for most organisations.
2. Upgrade to SharePoint Server Subscription Edition (SPSE)-Not Recommended
If regulatory or data-sovereignty requirements mean you must remain on-premises, SPSE provides a supported platform with regular feature and security updates.
