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

Message ID: MC1247891

[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.

[What you can do to prepare]

No action is required if your organization already uses automatic or recommended sensitivity labeling policies in Microsoft Purview Information Protection. Outlook mobile support is added automatically.

Admins may choose to:

• Review existing labeling policies in the Microsoft Purview portal to confirm correct scoping and label publishing.
• Ensure sensitivity labels are published to users who rely on Outlook mobile.
• Communicate this change to helpdesk or support teams.
• Review Microsoft Learn documentation for minimum supported Outlook mobile versions: Sensitivity label capabilities in Outlook – Minimum versions for sensitivity labels in Office apps | Microsoft Purview | Microsoft Learn

[Compliance considerations]
