MC1247891 - Outlook: Support for recommended and automatically applied sensitivity labels in Outlook for iOS and Android

Introduction

Outlook for iOS and Android is adding support for recommended and automatically applied sensitivity labels when you compose an email on your mobile device. With this release, we are extending Recommended Labels to Outlook mobile (iOS and Android), providing the same labeling experience users already have in Outlook on the desktop and web. For recommended labels, you’ll see a prompt to review and apply the suggested label. For automatic labels, they will be applied without needing any action from you. This ensures alignment with your organization’s Microsoft Purview Information Protection labeling policies when sensitive information is detected.

This message is associated with Microsoft 365 Roadmap IDs 557253 and 557254.

When this will happen

General Availability (Worldwide): We will begin rolling out in mid‑March 2026 and expect to complete by late March 2026.
