[Introduction]<\/b><\/p>\n

<\/p>\n

To maintain a high-quality and reliable experience for live Captions & Subtitles<\/b> in the Microsoft 365 PowerPoint app, Microsoft is upgrading the backend service that supports this capability. As part of this improvement, older Office client versions will no longer be supported. Updating to the minimum required PowerPoint version ensures continued accessibility, performance, and reliability.<\/p>\n

[When this will happen:]<\/b><\/p>\n

    <\/ul>\n

    Upgrade <\/b>by the end of September 2026<\/b><\/p>\n

      <\/ul>\n

      [How this affects your organization:]<\/b><\/p>\n

      <\/p>\n

      Who is affected:<\/b><\/p>\n

      <\/p>\n

        <\/p>\n
      • Organizations using Microsoft 365 PowerPoint app (Win32 or Mac)<\/b><\/li>\n

          <\/ul>\n

          <\/li>\n

          <\/ul>\n

          [What will happen:]<\/b><\/p>\n

          <\/p>\n

            <\/p>\n
          • Users on unsupported versions<\/b> will lose access to Captions & Subtitles<\/b> after the listed dates.<\/li>\n

            <\/p>\n

          • There is no change<\/b> for users on supported versions<\/b>.<\/li>\n

            <\/p>\n

          • No changes to default settings<\/b> or admin configuration are required.<\/li>\n

            <\/ul>\n

            [What you can do to prepare:]<\/b><\/p>\n

            <\/p>\n

              <\/p>\n
            • Review PowerPoint client versions across your organization (Windows and Mac).<\/li>\n

              • Plan upgrades ahead of September 2026<\/b>, especially for environments on managed or restricted update cadences.<\/li>\n

                <\/p>\n

              • Notify helpdesk and accessibility stakeholders.<\/li>\n

                <\/ul>\n

                [Compliance considerations:]<\/b><\/p>\n
