  • To use Copilot in Outlook, create a new email, choose “Daft with Copilot,” and compose a prompt to generate the content.
  • You can also open an existing email and click the “Summary by Copilot” to generate a summary of the email thread.
  • Also, while replying to an email, you can use Copilot to suggest a reply based on the content.

Outlook includes Copilot, and in this guide, I will teach you the steps to get started using the chatbot AI in Outlook (web), Windows, macOS, iPadOS, and mobile. (These instructions are focused on the web version of the email service, but the experience is the same across the experience.)

What’s Copilot in Outlook?

Copilot is a chatbot AI assistant that uses large language models (LLMs) to help you boost your productivity when composing and managing emails.

In Outlook, Copilot can generate drafts of emails with a simple prompt, summarize email threads by pulling the most important points of each email, and review your email to provide suggestions to improve it.

The chatbot AI in Outlook is a premium feature, meaning that you will need a subscription for Copilot Pro in addition to a Microsoft 365 Personal or Family subscription. Also, the feature is only available for the primary mailbox, and it’s not supported on mailboxes from Exchange Online.

In this guide, I will outline the steps to use Copilot in Outlook for Windows 11 and where supported. (Copilot is also available in Word.)

The draft feature doesn’t have a limit on the length of the prompt. However, the AI will scan the message or email threads for replies to generate a response, but there’s a limit on how deep the chatbot can process on long threads.

It’s important to note that this feature can only process a limited number of threads because of the amount of data the AI can process at one time. As a result, old emails may not be included in the final summary.

  1. Open Outlook.

Finally, remember that the AI can generate inaccurate responses. As such, it’s important to always review the content before sending it.
