## Summary

Microsoft will retire **Themes by Copilot** from Outlook worldwide between mid-to-late October 2026. The feature, which let users with a Copilot license generate and apply custom email themes, will vanish from the New Outlook app for Windows, Outlook.com on the web, and the macOS app. Microsoft did not disclose the reason but reports cite low adoption as a factor.

Existing themes remain active until users manually change them. Once a non-Copilot theme is selected, the Copilot-generated theme cannot be recovered. Copilot itself stays in Outlook for other tasks like email editing, but branding changes elsewhere—such as renaming Writing tools in Notepad—signal Microsoft’s broader push to deprioritize standalone Copilot integrations.

## Key points

- Microsoft removes Themes by Copilot from Outlook in October 2026, affecting Windows, web, and macOS versions
- Existing themes stay until users switch away; Copilot themes cannot be restored after deletion
- Copilot remains in Outlook for other functions, but Microsoft is scaling back Copilot-branded features across Windows

## Why it matters

This reflects Microsoft’s shift toward integrating AI tools more discreetly, reducing clutter in productivity apps. For users, it means fewer AI-driven customization options in Outlook, though core Copilot assistance persists.
