Copilot in Outlook works in the new Outlook for Windows, Outlook on the web and on mobile. It condenses a long email thread into a few points, drafts a reply from a short instruction, suggests tone and length, and before a meeting gathers related emails and files. With a business license it sees the employee's mail and calendar within the company's access rights. It helps people who receive dozens of emails a day with approvals, invoices and requests.

Tasks it handles well

Most useful for

Pitfalls to watch at work

A thread summary misses attachments and late edits in quoted text: check amounts and dates in the email itself
The reply draft picks up the tone of the previous email, including a sharp one: reread before sending
A personal Copilot Pro subscription on a work mailbox takes company email outside its tenant: work mail needs a business license

Billing

Not sold separately: included in Microsoft 365 Copilot for business (through the admin center or a Microsoft partner) and in Microsoft 365 Personal or Family with Copilot for individuals.
