SharePoint 2016 End of Life July 14, 2026: 6 Months to Act

The Countdown to July 14, 2026

Microsoft SharePoint 2016 will reach end of life on July 14, 2026. That is roughly six months from the time of this writing. Extended support ended on July 13, 2021, so the product has been in a maintenance-only phase for several years. This is not a Long-Term Servicing (LTS) release, and the latest cumulative update for this version is 16.0.5556.1005. For organizations still running SharePoint 2016, the decision window for migration or alternative support is closing fast.

A Realistic Migration Timeline

A migration from SharePoint 2016 to a newer on-premises version or to SharePoint Online typically takes several months from start to finish. Working backwards from July 14, 2026, consider the following phases:

• Assessment and planning (4–6 weeks): Audit your current farm, identify customizations, third-party add-ins, and content databases. Determine the target environment (SharePoint Subscription Edition or SharePoint Online).
• Proof of concept (4–6 weeks): Set up a test environment, validate compatibility, and test migration tools.
• Migration execution (8–12 weeks): Actual data migration, reconfiguration of services, and testing. This phase often overlaps with user acceptance testing.
• Change freeze and cutover (2–4 weeks): Schedule the cutover during a low-activity period, allow for rollback if needed.

Many organizations also face procurement cycles for new licenses or cloud subscriptions, which can add 4–8 weeks. If your fiscal year or change freeze periods (e.g., year-end holidays) intervene, that further compresses the timeline. A full migration starting today could comfortably fit, but any delay reduces the margin for error.

Risks of Running Past End of Life

After July 14, 2026, Microsoft will no longer provide security updates, hotfixes, or technical support for SharePoint 2016. Running an unsupported platform exposes your organization to:

• Unpatched vulnerabilities: New CVEs discovered after EOL will not be addressed by Microsoft. An exploit targeting SharePoint could put corporate data at risk.
• Compliance and audit failures: Regulatory frameworks such as PCI DSS, HIPAA, or SOX often require supported software. An EOL product may fail compliance scans.
• Lack of vendor support: No escalations, no hotfixes for critical bugs. If your farm breaks, Microsoft will not help.

These risks are not theoretical. Many IT teams have been caught off-guard by the end of a product’s lifecycle, scrambling for emergency options.

Third-Party Support: A Viable Safety Net

Third-party maintenance providers offer an alternative to running unsupported or rushing a migration under pressure. By contracting with a reputable third-party support vendor, you can continue receiving security patches and technical support for SharePoint 2016 beyond Microsoft's end-of-life date. This removes the immediate deadline pressure and lets your team plan and execute a migration on their own schedule.
