Microsoft has issued a clear reminder that Microsoft Access 2016 and Access 2019 — like many Office-era products — will reach official end of support on October 14, 2025, meaning security updates, bug fixes, and technical assistance stop on that date and users who remain on these versions will assume growing operational and security risk.

Background
What Microsoft announced and why it matters
Microsoft’s lifecycle calendar lists Access 2016 and Access 2019 under the Fixed Lifecycle Policy with an Extended End Date of October 14, 2025. After that date Microsoft will not ship security patches, quality updates, or provide technical support for those products. This end-of-support date is part of a broader set of retirement moments that also includes Windows 10 and multiple Office-era servers and productivity products. Microsoft has repeatedly urged customers to plan migrations now, saying that while the apps will continue to run, continuing to use unsupported builds exposes individuals and organizations to serious and potentially harmful security risks. The company’s official guidance explicitly notes there will be no Extended Security Updates (ESU) program for Office 2016/2019 — this is a departure from past practices that offered paid ESU bridges for some Windows releases.What “end of support” actually means for Access users
- No more security updates: Newly discovered vulnerabilities affecting Access 2016/2019 will not be patched by Microsoft after October 14, 2025. Systems running those products will therefore become progressively more attractive to attackers.
- No bug fixes or reliability patches: Stability or compatibility issues that appear after the cut-off will not be remediated by Microsoft.
- No technical support: Phone, chat, and official Microsoft support for these specific versions will end.
- Potential service degradation: As Microsoft evolves cloud services and back-end APIs, older clients may experience reliability or compatibility problems when interacting with modern Microsoft 365 services.
The Microsoft-prescribed migration routes
Microsoft’s public guidance presents three primary migration paths for Access users:- Move to Microsoft 365 Apps (subscription-based): Microsoft highlights that Microsoft 365 Apps include the desktop version of Access alongside cloud-connected features, AI-powered services, and 1 TB of OneDrive storage per user for subscribers. The company positions this as the recommended route for most customers who want continuous feature updates and security.
- Adopt Office LTSC 2024 (volume-licensed, perpetual): For organizations that need a disconnected or long-term static environment, Office LTSC 2024 is available as a one-time-purchase on a volume-licensing basis and includes Access. LTSC releases receive a fixed five-year support window but do not receive feature updates beyond the initial release; they are appropriate for locked-down or regulated scenarios.
- Use third-party mitigation and micropatching services: A growing market of security vendors offers in-memory micropatches and managed mitigations to extend practical security coverage for unsupported products. These are not vendor-supported by Microsoft and carry trade-offs for compliance and long-term maintenance. (techspot.com)
Why Microsoft is pushing Microsoft 365 — and what you get
Microsoft’s messaging is consistent: the cloud-first, subscription model enables ongoing security, rapid feature delivery, and deeper integration with AI and cloud services. Microsoft’s marketing and support pages list the primary benefits of moving to Microsoft 365 Apps:- Continuous security updates and feature improvements — delivered automatically.
- AI-powered tools and connected experiences—including enhanced Editor experiences and cloud-assisted capabilities across Word, Excel, and Access.
- 1 TB OneDrive storage per user for cloud file access and synchronization.
- Cross-device access and easier collaboration, plus centralized management and enterprise-grade security controls in business SKUs.
Alternatives and the trade-offs
Office LTSC 2024 — the “staying on-premises” choice
Office LTSC 2024 provides a path for customers who must avoid cloud connectivity or prefer a perpetual license model. It includes Access on Windows and is supported under the Fixed Lifecycle Policy for five years (through 2029). However, Office LTSC:- Does not receive ongoing feature updates after release.
- Lacks many cloud-backed productivity and AI features present in Microsoft 365 Apps.
- Is targeted at volume-licensed deployments (not consumer one-off purchases). (support.microsoft.com)
Third‑party micropatching (0patch and peers)
Third-party vendors such as 0patch have announced plans to “security-adopt” Office 2016 and Office 2019 to provide micropatches after Microsoft’s cut-off. These micropatches work by applying tiny, in-memory fixes that target specific vulnerabilities without shipping full vendor-signed installers.Advantages:
- Rapid mitigations for zero-day and post-EoS vulnerabilities.
- Little or no downtime: many micropatches do not require reboots.
- Not a substitute for vendor support: these patches are unofficial and may not cover every vulnerability or behavioral issue.
- Compliance and legal implications: regulated industries may not accept third-party patching as a compliance-equivalent to vendor patches.
- Operational overhead and vendor lock-in: deploying and managing a new security agent across fleets introduces management complexity and recurring costs. (blog.0patch.com, learn.microsoft.com, microsoft.com, techspot.com)
A practical migration checklist (recommended timeline)
- Inventory all Access installations, runtimes, and dependent services (Month 0–1).
- Categorize applications by criticality: mission-critical, business-critical, and low-risk (Month 0–1).
- For mission-critical apps, run compatibility tests with Microsoft 365 Apps and Office LTSC 2024 in a sandbox (Month 1–3).
- Evaluate back-end migrations (move data to Azure SQL, SQL Server, or Dataverse) and test Access front-end connectivity (Month 2–6).
- Create a staged migration plan: pilot users → phased roll-out → decommission legacy installs (Month 3–9).
- Implement security compensating controls for any remaining legacy endpoints until fully migrated (ongoing).
- Final cutover and retirement of unsupported Access versions before or on October 14, 2025 where possible. If not feasible, decide whether to use a micropatch vendor as an interim measure and document compensating controls (Month 9–12).
Enterprise-level considerations
Don’t underestimate third‑party risks
Third-party micropatching can fill critical gaps quickly, but enterprises must perform vendor risk assessment, integration testing with existing endpoint management solutions, and legal/compliance reviews. Micropatches modify process memory at runtime — an advanced technique requiring careful validation in sensitive or high-availability environments.Plan for custom code and add-ins
Many organizations rely on custom macros, COM add-ins, or third-party integrations with Access. Migration projects must include:- Code scanning and refactoring (VBA → .NET or modern web-based front-ends where warranted).
- Regression testing — especially around data integrity and transactional behavior.
- Change management and user training for new workflows.
Licensing and procurement
- Enterprise Microsoft 365 licensing can be complex; consult Microsoft Sales Support for upgrade incentives and volume discounts when planning migrations.
- Office LTSC requires volume licensing agreements and is often a better fit for specialized on-premises scenarios. (learn.microsoft.com)
Security posture: measurable risks of staying on Access 2016/2019
- Unsupported software is a known attack surface: adversaries prioritize targets that will not receive vendor fixes.
- Cyber-insurance and regulatory frameworks increasingly penalize unpatched or unsupported endpoints — expect higher premiums or non-compliance flags.
- Legacy clients can exhibit compatibility problems with modern authentication and encryption protocols over time, increasing operational friction. (learn.microsoft.com)
