Outlook already drafts, summarizes, and helps you catch up on email with Copilot. The newest update turns it into something more interesting: a coach that reviews your email before you send it, explains what could be stronger, and can apply suggested improvements directly to your draft — while you stay in charge of which changes land.

Here’s what’s new, why this one is a genuine upgrade for anyone who writes email, and three ways to put it to work today.

1. Coaching feedback that explains its reasoning

Copilot’s new coaching feedback in Outlook reviews your draft and surfaces suggestions inside the Copilot chat pane — not as a generic “make this better” rewrite, but as specific, explained recommendations: the tone is softer than your usual style, the ask is buried in paragraph three, two sentences can be cut, the closing line could be warmer.

That “explain the reasoning” piece is what makes it feel less like autocorrect and more like a thoughtful colleague who happens to read quickly.

2. Apply changes in place with a single click

Once Copilot proposes a change, you don’t have to copy-paste anything. You can apply suggestions directly to the email — pick which changes you want and Copilot updates the draft in place. Don’t love a suggestion? Skip it. Want them all? One click.

This is the detail that matters most for daily use. The difference between “Copilot writes my email” and “Copilot helps me write my email” is whether you stay in the driver’s seat, and this applied-in-place flow keeps you there.

3. It works with your voice, not against it

Because the feedback is explained, you can learn the kind of edit Copilot is suggesting and choose whether to adopt it. Over time, you’ll see patterns — maybe Copilot consistently flags your passive voice on Mondays, or suggests your sign-offs could be warmer when you’re emailing external partners. That’s genuinely useful feedback even on emails you don’t ask Copilot to coach.

Educators especially benefit here: the difference between a parent email that lands well and one that doesn’t is often two or three word choices. A quick coaching pass catches those.

Quick example: a parent email that lands better

Imagine you’re a middle-school teacher writing a parent about a student’s late homework. Your first draft might read:

Hi Mr. Carter — I wanted to flag that Jayden hasn’t submitted the last two science assignments. Could you follow up?

Open the Copilot coaching pane and it might flag:

• Tone note: the opening lands as slightly critical; a warmer lead softens it.
• Clarity note: “flag” is corporate — “let you know” is friendlier.
• Action note: the ask is clear but gives the parent nothing to work with. A suggested follow-up (“a quick check-in tonight would really help”) makes it easier to say yes.

Apply the suggestions and the revised draft becomes:

Hi Mr. Carter — I wanted to let you know Jayden hasn’t submitted the last two science assignments. He’s a strong thinker when he engages, so I’d love to keep him on track. A quick check-in at home tonight would really help — I’m happy to send the assignment links if useful.

Same information. Much better landing.

Next step

Open any email you’re drafting in Outlook on the web or desktop and look for Copilot in the ribbon or compose pane. Click Coaching feedback or simply ask Copilot chat to “review this draft and suggest improvements I can apply.” Start with a low-stakes email — a thank-you note, a meeting reschedule — so you can see the flow before you use it on something critical.
