SharePoint 2016 EOL July 14, 2026: Budget Planning Guide

What "End of Life" Means for SharePoint 2016

Microsoft SharePoint 2016 will reach end of life on July 14, 2026. After that date, Microsoft will no longer provide security updates, non-security hotfixes, or technical support for the product. Active support ended on July 13, 2021, so the product has been in extended support (which still includes security patches) for the past several years. This is not a long-term servicing (LTS) release; the latest build in this line is 16.0.5556.1005. For more details, see the Microsoft SharePoint lifecycle page.

For budget planners, this date is critical because it falls in the next fiscal year for most organizations. The decision to fund a migration, purchase extended support, or engage a third-party support provider must be made now to have the line item ready when the new budget cycle begins.

The Migration Reality: What Upgrading Typically Involves

Upgrading from SharePoint 2016 is not a simple patch. A typical migration to a newer version—such as SharePoint Server Subscription Edition or SharePoint Online—requires:

• Infrastructure assessment: Checking hardware, databases, and customizations for compatibility.
• Content and database migration: Moving terabytes of data, often requiring multiple test runs.
• Custom code and third-party add-in remediation: Solutions built for SharePoint 2016 may break on newer versions and need redevelopment.
• User acceptance testing: Validating that all business workflows function correctly.
• Training and change management: Users and administrators must learn the new interface and capabilities.

A project of this scope can take 6 to 18 months depending on the size and complexity of the environment. Starting now means the migration may still be incomplete by the July 2026 deadline.

Why Many Teams Miss the Migration Window

Despite clear end-of-life dates, many organizations fail to migrate in time. Common reasons include:

• Competing priorities: IT departments often juggle multiple system upgrades, cloud migrations, and security initiatives.
• Budget delays: Migration projects require significant capital; procurement cycles can stretch beyond the planned start date.
• Scope creep: The discovery of custom applications or orphaned content adds months to the timeline.
• Vendor dependency: Microsoft may not guarantee a seamless upgrade path, especially for heavily customized farms.
• People bandwidth: Key SharePoint administrators are often the same people who need to migrate the system, creating a bottleneck.

Any one of these factors can push the migration past the EOL date, leaving the environment unsupported and exposed.

Comparing the Costs: Migration, Vendor Extended Support, and Third-Party Support

When the EOL date arrives, you have three main options:

1. Migrate to a Supported Version

• Cost: High, often six or seven figures for large enterprises. Includes software licenses, consulting fees, hardware upgrades (if on-premises), and internal labor.
• Timeline: 6–18 months; must start before July 2026 to avoid a gap.
• Risk: Delays can leave the old system unsupported for a period.

2. Purchase Vendor Extended Support (if available)

Microsoft does not typically offer custom extended support agreements for SharePoint on-premises; these are rare and expensive, often costing a multiple of the original license cost per year. They may also require purchasing additional services or licenses.

3. Engage a Third-Party Support Provider

Third-party support providers can maintain your SharePoint 2016 environment after the official end-of-life date. Services typically include:

• Security patches and critical bug fixes.
• 24/7 technical support from engineers who know the product.
• Continued compatibility with third-party integrations.

Cost is usually 40–60% less than the annual cost of a vendor maintenance agreement or a forced migration. The provider handles the support burden, freeing your team to plan a migration at a realistic pace.

What to Put in Your Budget Request Now

For the next fiscal year, your budget request should include a line item for the SharePoint 2016 support strategy. At minimum, include:

• A proposed start date for the migration (if you intend to move) with a realistic timeline that accounts for testing and cutover.
• Contingency funds for an additional 12–24 months of support if the migration slips.
• A comparison of costs for migration, vendor extended support, and third-party support, with the latter as a baseline.

By including a third-party support option, you give leadership a risk-mitigated alternative that doesn't lock you into a vendor's schedule or pricing.

Get a Third-Party Support Quote as a Benchmark

Before you enter renewal or migration negotiations, get a third-party support quote for your SharePoint 2016 environment. This gives you a concrete number to compare against the cost of migrating or buying extended support. It also helps you budget accurately for the next 12–24 months.
