Microsoft pulls plug on Copilot themes in New Outlook, bets big on chat

Microsoft pulls plug on Copilot themes in New Outlook, bets big on chat

If you've been enjoying the AI-generated themes in the new Outlook, brace yourself: they're going away. According to Windows Latest, Microsoft will remove the Copilot theme feature globally in mid-to-late October 2026. The change affects all platforms—new Outlook on macOS and Windows, as well as the web version at Outlook.com.

So what exactly is a Copilot theme? It's an AI-powered customization tool that lets you type a few words or pick a preset, and Copilot whips up a visual style that completely changes how Outlook looks. Microsoft once touted it as a headline feature for Windows 10 and 11. But here's the rub: media reports suggest that actual usage was far below Redmond's expectations. Click-through and retention rates just couldn't justify the investment, so out it goes.

Farewell to 'Wrap up your day'

It's not just themes that are getting the boot. Another feature, "Wrap up your day," is also being shown the door. This tool would proactively ask Copilot to generate a quick inbox summary and tuck it into the right sidebar. With its removal, Outlook's auto-summarize capability is effectively retired too.

A new direction: chat first, cosmetics later

Instead, Microsoft is pivoting to a simpler, chat-centric design. Later this month, the company plans to update the Copilot experience in Outlook, reorganizing navigation, conversation layout, and Work IQ controls. The message is clear: Microsoft is shifting its bet from "let AI change the skin" to "let AI do real work in the chat window." Interface beautification is giving way to practical assistant capabilities.

Key Points

  • Copilot themes in new Outlook will be discontinued globally in mid-to-late October 2026.
  • The removal affects macOS, Windows, and web versions of Outlook.
  • Low usage and poor retention reportedly drove the decision.
  • "Wrap up your day" auto-summary feature is also being retired.
  • Microsoft is refocusing on a chat-centric Copilot experience with practical tools.

It's a classic case of style versus substance. While AI-generated themes were a flashy way to personalize your inbox, they apparently didn't stick. Now, Microsoft wants Copilot to be less about looks and more about getting things done. Will users embrace the change? Only time will tell—but for now, it's clear that Redmond is prioritizing function over form.
