Copilot now available in classic Outlook for Windows 10 and 11

Last Ignite we showed our plans for Copilot in Outlook and how the new Outlook for Windows would get the most recent features first.

We also know that our customers still rely on the classic version of Outlook for a lot of their work and to improve their Copilot experience we have been rolling out Copilot features into classic Outlook over the last few months.

For future Copilot features, we will continue to release first in the new Outlook for Windows and web, with Mac and mobile fast following, and classic releasing between 3 and 12 months after the first roll out.

Copilot in classic Outlook for Windows is already available for most customers in Current Channel or Monthly Enterprise Channel.

Available features include:

Summarize by Copilot Imagine sending an email, taking a short break and coming back to a very active thread with multiple replies. You could scroll back to the first response and start reading or Copilot can quickly summarize the thread for you, so you can catch up on what happened in with a few bullet points in minutes. Copilot even points out where it got the information so you can get more details if needed. To access summarize, select the “Summarize” button on the top right of the reading pane after you open a message. This feature is available in build 16.0.17028.10000 in Current Channel and Monthly Enterprise Channel.

Coaching by Copilot An additional set of eyes on an important email you are writing can help you make sure you are communicating the right ideas. When busy schedules and due dates mix up, coaching by Copilot can be that set of extra eyes and provide suggestions to help you communicate your ideas with the right tone, clarity, and make sure the reader sentiment is the intended. To get coaching, once you have drafted a message, select the Copilot icon in the ribbon and then “Coaching by Copilot”. Available in build 16.0.17231.20182 in Current Channel and Monthly Enterprise Channel.

Starting in June, Copilot for Microsoft 365 chat experience (Microsoft 365 Roadmap ID 388753) is coming to classic Outlook for Windows.

We understand that classic Outlook is an important tool for many people, and we hope to bring more Copilot features into classic Outlook. While each platform has its own dev time, we expect that key Copilot features that come to new Outlook for Windows, web, mobile, and Mac will also come to classic Outlook within a reasonable follow-up timeline depending on the feature.
