Microsoft is adding AI-powered themes to Outlook today. Called “Copilot Themes,” this AI-powered feature will require a Copilot Pro or Business license to add a more personalized look to the Microsoft email client.

The themes will appear on Outlook for Windows, macOS, iOS, Android, and the web, and are designed to make “Outlook more beautiful and accessible,” according to Microsoft.

You’ll be able to create a theme based on weather or locations, and these can dynamically update every few hours, daily, weekly, or monthly. “If you’ve enabled location permissions in Outlook, the My Location theme will provide you with images uniquely inspired by your location, dynamically updating for you as you head out the door on a trip or vacation,” says Microsoft.

Each AI-generated theme has a background wallpaper in the desktop version of Outlook or in the top section of the iOS and Android apps. There is also an accent color that themes the rest of the Outlook client.

Microsoft is also releasing a collection of non-AI themes for everyone without a Copilot license. The collection includes green, red, and purple themes that are available on the web, PC, Mac, and mobile versions of Outlook.
