The average professional spends two hours a day on email. Most of that time is not reading important messages — it is searching, drafting, summarising, and scheduling. Copilot in Outlook cuts that work in half.
This guide covers every major Outlook Copilot feature in 2026 — from drafting emails in seconds to generating meeting prep briefs.

Draft Emails in Seconds with Copilot
How to Use Draft with Copilot
When composing a new email, click the Copilot icon in the toolbar. Describe what you want in plain English:
- “Write a professional follow-up to Sarah about the contract approval overdue since last week”
- “Draft a brief, polite decline to a meeting request and suggest an alternative time next week”
- “Ask the marketing team to share the Q2 campaign performance report by Friday”
Adjust the Tone (Formal, Casual, Direct) and Length (Short, Medium, Long) before inserting.
Coaching by Copilot: Improve Before You Send
Before sending any important email, click Coaching by Copilot. It analyses your draft and gives feedback on tone, clarity, reader perception, and specific rewrite suggestions.
Thread Summary: Catch Up Without Reading Everything
Open any long email chain and click Summary by Copilot. You get the main topic, key decisions, outstanding questions, and who said what — with attribution and clickable links to source emails.
An overdue thread now takes 10 seconds to catch up on, not 10 minutes.
Calendar Intelligence: Smarter Scheduling
AI-Recommended Meeting Times
Copilot analyses your calendar and suggests the best available slots, protecting your focus blocks so meetings land where they least disrupt deep work.
Meeting Preparation Briefs
Click any calendar event and choose “Prepare with Copilot.” It searches your emails, Teams messages, and documents for context — previous discussions, open action items, shared files — and returns a structured briefing.
