On October 14, 2025, Microsoft is ending support for Office 2016 and 2019.<\/strong> In practical terms: no more security patches, no more official support, and decreasing compatibility with cloud services (Outlook\/Exchange Online, OneDrive, Teams, connectors). For an SMB, staying on these versions means accepting an increased risk of vulnerabilities and unpredictable service disruptions.<\/p>\n\n\n\n

The Essentials<\/strong><\/strong><\/h3>\n\n\n\n
    \n
  • Office 2016 and Office 2019 reach end of support on October 14, 2025.<\/li>\n\n\n\n
  • There is no extension or ESU for these perpetual versions.<\/li>\n\n\n\n
  • The apps will continue to work, but the security\/compatibility risk increases after 2025.<\/li>\n<\/ul>\n\n\n\n

    Your Replacement Options<\/strong><\/strong><\/h2>\n\n\n\n
      <\/ul>\n\n\n\n

      1) Microsoft 365 Apps (subscription)<\/strong><\/strong><\/h3>\n\n\n\n

      Latest features (and AI depending on license), best Exchange\/SharePoint\/OneDrive compatibility, continuous updates. Recommended by default for SMBs\/NPOs.<\/p>\n\n\n\n

      2) Office LTSC (perpetual license)<\/strong><\/strong><\/h3>\n\n\n\n

      Office LTSC 2021 (support until October 13, 2026) and Office LTSC 2024 (released 2024, 5 years of support). Ideal for fixed\/offline workstations.<\/p>\n\n\n\n

      3) Web-based office suites \/ alternatives<\/strong><\/strong><\/h3>\n\n\n\n

      Office for the web, ChromeOS Flex + Google Workspace depending on profile, or LibreOffice\/OnlyOffice suites for specific needs.<\/p>\n\n\n\n

      Technical impacts to anticipate<\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n
        \n
      • Security: no more patches for Office 2016\/2019 after 2025 (macro\/VBA, formats) \u2192 increased attack surface.<\/li>\n\n\n\n
      • Interoperability: older Outlook clients = degraded compatibility\/security with modern cloud services.<\/li>\n\n\n\n
      • Add\u2011ins & macros: test VSTO\/WEB add-ins and VBA in the target environment (Microsoft 365 Apps or LTSC).<\/li>\n<\/ul>\n\n\n\n

        Recommended migration plan<\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n
          \n
        1. Map versions\/editions, add\u2011ins, templates, macros, fonts.<\/li>\n\n\n\n
        2. Choose the target: Microsoft 365 Apps (default) or Office LTSC for constrained machines.<\/li>\n\n\n\n
        3. Pilot (10\u201315%): validate critical documents (heavy PPTX, Excel PivotTables, mail merges, add\u2011ins).<\/li>\n\n\n\n
        4. Deployment: via Intune\/ODT for Microsoft 365 Apps, or ISO for LTSC; choose the right update channel.<\/li>\n\n\n\n
        5. Quick training: co\u2011authoring, OneDrive\/SharePoint, secure sharing.<\/li>\n\n\n\n
        6. Removal: uninstall legacy versions, lock unsigned macros.<\/li>\n<\/ol>\n\n\n\n

          FAQ \u2014 Office 2016\/2019<\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n
          Can I continue using Office 2016\/2019 after 2025?<\/summary>\n

          Yes, but without security patches: at your own risk. Microsoft recommends Microsoft 365 Apps or a recent LTSC.<\/p>\n<\/details>\n\n\n\n

          Are there ESU (Extended Security Updates) for Office 2016\/2019?<\/summary>\n

          No, Microsoft has not planned ESU for these Office products.<\/p>\n<\/details>","protected":false},"excerpt":{"rendered":"
