No more wading through old threads or switching apps to copy numbers into an email. With Draft with Copilot, Outlook now builds a complete, personalized reply—pulling context from the very conversation, recent meetings, attached files, even connected SharePoint docs. Below is a hands-on guide to the feature as it stands in May 2025, along with practical tips to turn AI-generated prose into polished professional communication.

1 · What the Context-Aware Draft Feature Does

Reads the full conversation, attachments, and calendar invites to understand purpose, tone, and outstanding questions.
Suggests a subject line, greeting, body, and closing that reference key details—dates, amounts, names—without you hunting for them.
Offers refinement buttons (Shorten, Formalize, Add bullet list, Translate, and more) so you can tailor the draft in seconds.

2 · Step-by-Step: Generating Your First Contextual Draft

Step	Action in Outlook
1	Click Reply or Compose on desktop, web, or mobile.
2	In the new message pane, select Draft with Copilot.
3	Choose Include thread context (on by default) and, if needed, toggle Use calendar & files.
4	Type a brief prompt such as “Confirm shipment date and next payment terms.”
5	Review the generated draft. Use buttons like Make concise or Add friendly tone.
6	Edit any remaining details, check attachments, then send.

Tip Mention any required call-to-action in your prompt (“ask for a signed NDA by Friday”) so Copilot inserts it explicitly and prominently.

3 · Under the Hood: Where Copilot Looks for Context

Current thread — extracts quoted commitments, milestones, and questions.
Attachments — scans the latest versions of Word, Excel, and PDF files for figures like amounts or model versions.
Calendar — references upcoming or past meetings (“as we agreed in yesterday’s kick-off call”).
Recent files — surfaces slides or spreadsheets you worked on in the last 48 hours if they match the topic.

All context stays within your organization’s compliance boundary; Copilot only accesses what you already have permission to view.

4 · What’s New in 2025

Dynamic tone control — a slider lets you mix formality levels (“70 % friendly, 30 % formal”) and watch the draft shift live.
Smart CC suggestions — Copilot proposes additional recipients based on who contributed in related Teams chats or documents.
Inline fact-check — hover over highlighted figures to see the source file or message, reducing copy-paste errors.
Automatic language match — detects the language of the original sender and drafts the reply in the same tongue.

5 · Five High-Impact Use Cases

Sales follow-ups — insert product specs from last email, confirm price, and propose next-step meeting times auto-pulled from your free-busy.
Project status updates — compile task progress from Planner, then CC stakeholders Copilot identifies.
Invoice reminders — pull due-date and balance due from attached PDF invoice, adding a polite pay-by date.
Customer support escalations — summarize troubleshooting steps already tried and propose remaining solutions, trimming out technical jargon for clarity.
HR offer letters — draw compensation numbers from the attached package overview, maintain the company’s approved tone, and attach doc links automatically.

6 · Best Practices for Reliable Results

Do	Don’t
Give a crisp prompt — specify intent: “remind,” “confirm,” “propose next call.”	Assume Copilot infers subtle policy constraints; state them.
Review facts — glance at hover cards to verify figures and dates.	Let typos slip—proofread like any important email.
Adjust tone early — apply Formal/Friendly buttons before heavy editing.	Leave placeholders (“[amount]”) unedited; fill every blank.
Attach supporting docs — Copilot references them in text and as attachments.	Rely on context if the draft addresses a new subject line; provide extra detail.

7 · Looking Ahead

Microsoft’s roadmap hints at voice-draft mode—speak your intent and Copilot builds the message, plus meeting-aware hand-offs that auto-sync summaries from Teams Intelligent Recap into the draft. A tighter Planner and To Do integration is also slated to convert detected action items directly into assignable tasks.
