[What and why]<\/b><\/p>\n

We are retiring Themes by Copilot in Microsoft Outlook. Themes by Copilot currently allows users with a Copilot license to create and apply a Copilot-generated theme in Settings. As part of this change, Themes by Copilot will be removed from Settings, and users will no longer be able to select or return to a Theme by Copilot after changing to a different theme.<\/p>\n

[Rollout schedule]<\/b><\/p>\n

    \n
  • General Availability (Worldwide):<\/b> Retirement begins in mid-October 2026 and is expected to complete by late October 2026.<\/li>\n<\/ul>\n

    [Impact on your organization]<\/b><\/p>\n

    Who is affected<\/i><\/p>\n

      \n
    • Users with a Copilot license.<\/li>\n<\/ul>\n

      Platforms and services<\/i><\/p>\n

        \n
      • New Outlook for Windows<\/li>\n

      • Outlook for iOS<\/li>\n
      • Outlook for Mac<\/li>\n
      • Outlook on the web<\/li>\n<\/ul>\n

        What will happen<\/i><\/p>\n

          \n
        • Themes by Copilot will be removed from Settings. Users who are currently using a Theme by Copilot will retain their current theme until they change it.<\/li>\n
        • Themes by Copilot configured to automatically refresh will remain applied but will stop refreshing. Users will retain the current theme imagery until they change their theme.<\/li>\n
        • Users can change from their existing Theme by Copilot to a non-Copilot theme but cannot return to a Theme by Copilot after doing so.<\/li>\n<\/ul>\n

          [Action required and recommendations]<\/b><\/p>\n
