Before enabling Copilot in Outlook, ensure the following:

  • You have an active Microsoft 365 subscription.

  • You have a valid Copilot subscription (Microsoft 365 Copilot or Copilot Pro).

  • Both subscriptions are linked to the same Outlook.com / Microsoft account.

  • Your Outlook is updated to the latest version (preferably New Outlook or Outlook on the Web).


2. Enable Copilot in Outlook

Option A: Outlook (Desktop – Classic)

  1. Open Outlook.

  2. Go to File → Options.

  3. Under Compose messages, check Enable Microsoft 365 Copilot.

  4. If not visible, click Editor Options → Proofing and select Use Copilot to help me write better emails.

Option B: New Outlook / Outlook on the Web

  • Sign in with your licensed Microsoft 365 account.

  • The Copilot icon will appear in the toolbar (Message composer, Thread summary, Calendar items).


3. Features Available in Outlook with Copilot
