Body (from Message Center)

Updated April 29, 2026: We have updated the content and timeline. Thank you for your patience.

[Introduction]

Stay on top of your inbox with the new Microsoft 365 Copilot voice experience in the Outlook mobile app—simply open Copilot, tap Voice, and manage your messages through a natural, conversational flow. Ask Copilot to summarize your recent unread emails and then take action like flagging, pinning, archiving, or marking as read—all without the hassle of navigating your inbox by hand. You can interrupt or redirect Copilot at any point in the conversation:

Read an email thread from start to finish or provide a more detailed summary
Ask follow-up questions
Take a triage action for a specific email – flagging, pinning, archiving, or marking as read

The end result

A new way to manage your Outlook mobile inbox that is conversational, hands-free, and convenient for working on-the-go, and more accessible than ever.
