Microsoft to Retire AI Theme Feature in Outlook
Microsoft will globally disable the AI-powered Copilot theme feature in Outlook in mid-to-late October 2026. This change affects new versions of Outlook across Windows, macOS, and the web.
Microsoft is set to globally discontinue the AI-powered Copilot theme feature within Microsoft Outlook in mid-to-late October 2026. The move impacts the updated versions of Outlook for Windows and macOS, as well as the Outlook.com web interface.
The Copilot theme feature allowed users to generate custom visual themes for their Outlook interface based on text prompts. It was introduced as a key AI-driven personalization option for the revamped email client.
Additionally, Microsoft plans to remove the "Wrap up your day" feature, which provided a summary of incoming emails. Industry observers speculate that low adoption rates may have contributed to the decision to retire these AI functionalities.
Microsoft intends to introduce an updated Copilot experience in Outlook in October 2026, focusing on a simplified, chat-centric design with improvements to navigation and productivity controls.
