Copilot in Outlook can draft replies, summarize long threads, coach your tone, and turn an email conversation into a meeting invite. It appears only for accounts with eligible Microsoft 365 Copilot access.
Does this affect you?
Use this for Outlook on the web and the new Outlook for Windows with a work or school account licensed for Microsoft 365 Copilot. Personal Outlook.com and basic Microsoft 365 plans may not include it.
Make sure Copilot is turned on and visible
Start with licensing and the visible button.
- Confirm your organization has assigned a Microsoft 365 Copilot license to your account.
- Open Outlook on the web or the new Outlook for Windows and sign in with that work or school account.
- Open an email thread or compose a new message.
- Look for the Copilot icon in the compose ribbon, message header, or thread toolbar.
- If it is hidden, check ribbon settings or ribbon display options.
- If it still does not appear, sign out and back in, restart Outlook, or try outlook.office.com.
Use Copilot everyday features
These are the common starting points.
- Draft an email: Open Copilot in a new message, choose Draft, describe what to say, generate the draft, then adjust length or tone.
- Summarize a thread: Open a long conversation and choose Summary by Copilot to get key points and references back to messages.
- Get coaching: Write your own draft, then use Coaching by Copilot for tone, clarity, and reader-perception suggestions.
- Schedule with Copilot: From an email thread, choose Schedule with Copilot to create a meeting title, agenda, and attendee list from the conversation.
More control
Copilot chat may appear in Outlook
Some accounts show a Copilot chat pane in Outlook where you can ask about calendar items or find email related to a topic without leaving Outlook.
Licensing can be staged
Microsoft 365 Copilot is licensed per user. It is normal for some people in the same organization to have it before others.
Review before sending
Copilot does not send messages without your review, but it can misread sarcasm, old context, or a long thread. Check names, dates, promises, and tone before sending.
