How to Draft an Email Quickly with Copilot
Most emails are 80% routine and 20% specifics. Copilot handles the routine 80% in seconds — you add the 20% that needs your judgement.
What it is
Drafting emails is the most everyday Copilot use case for most knowledge workers. A request, a follow-up, a polite refusal, a status update — these are emails you’ve written hundreds of times. Copilot can draft them faster than you can, in the right tone, with the right structure. You add the specific details, check the result, and send.
The skill is giving Copilot enough context to produce something useful. ‘Write an email about the meeting’ produces generic mush. ‘Write a short email to my manager confirming I can attend the strategy session next Thursday at 2pm, and asking whether I should bring the Q3 numbers’ produces something almost ready to send. The more specific you are about audience, purpose, tone, and details, the less editing you’ll need to do.
Where Copilot saves the most time isn’t speed of typing — it’s overcoming the small friction of starting. Many emails sit half-written for an hour because you can’t quite work out how to phrase the awkward bit. Copilot drafts the awkward bit in two seconds. You read it, make it more ‘you’, and hit send. The friction is gone.
When to use this
- When you need to send a routine email and don’t want to think about how to phrase it.
- When you’re stuck on the right opening or closing line.
- When you need to write something polite about a difficult situation.
- When you want a draft to react to, rather than starting from scratch.
How to do it
- Open Outlook (or Copilot Chat with your Outlook context).
- Tell Copilot the recipient, the goal, and the tone (friendly, firm, formal, brief).
- Provide the specific details Copilot can’t know — names, dates, numbers, requirements.
- Ask for a draft, then refine: shorter, more direct, more polite, different opening.
- Add anything Copilot got wrong or missed.
- Read the final version aloud — does it sound like you?
- Send.
Best practices
- Tell Copilot the outcome you want. ‘Approve’, ‘confirm’, ‘decline gracefully’, ‘request more info’.
- Specify the tone. Same content, different tone, very different email.
- Include specific details. Names, dates, numbers — Copilot can’t guess these.
- Always read before sending. Copilot can sound great but be wrong on facts.
Common mistakes
- Sending Copilot’s draft unedited. Even good drafts need your review for tone and accuracy.
- Pasting confidential information into prompts. Check your tenant’s policies before doing this with sensitive content.
- Generic prompts produce generic emails. ‘Write an email’ is too vague. Be specific.

How do I use Copilot to draft an email in Outlook?
In Outlook, click Draft with Copilot in a new message. Type what the email needs to say (e.g. ‘declining a meeting, polite, suggest next week’). Copilot generates a draft you can edit, refine, or regenerate. Adjust tone using the Copilot tone slider — Casual, Neutral, Formal.
Can Copilot read the email I’m replying to?
Yes — Copilot grounds replies in the original message. Click Draft with Copilot on a reply, and Copilot references the email thread automatically. You can also highlight a specific section to focus Copilot on just that part.
Why do my Copilot-drafted emails sound robotic?
Default Copilot tone is over-formal, especially in professional contexts. Three fixes: use the Casual tone setting, give Copilot specific instructions (‘write like I’m talking to my colleague, not my CEO’), and edit the draft — never send Copilot’s output verbatim if it sounds nothing like you.
Can Copilot match my personal writing style?
Yes — Copilot uses Work IQ to study your past sent emails and adapts tone and vocabulary. The match is approximate, not perfect. For high-stakes emails where the voice has to be unmistakably yours, treat Copilot’s output as a first draft and rewrite the parts that don’t sound like you.
