Updated August 7, 2025: We have updated the timeline. Thank you for your patience.
Introduction
Outlook Mobile for iOS and Android will soon support Data Loss Prevention (DLP) policy tips and enforcement. This update helps users avoid accidental data leaks by providing inline alerts or pop-ups when sensitive content is detected—based on admin-configured DLP rules. This enhancement brings DLP behavior in Outlook Mobile in line with Outlook for desktop and web, ensuring consistent compliance enforcement across platforms.
This message is associated with Microsoft 365 Roadmap ID 496146.
When this will happen
General Availability rollout will begin in early August 2025 (previously mid-August) and is expected to complete by early September 2025.
How this affects your organization
With this update, organizations using Microsoft Purview DLP policies will see those policies enforced in Outlook Mobile. When users attempt to send messages containing sensitive information—such as credit card numbers or national IDs—they will receive policy tips or blocking dialogs, depending on how the policy is configured.
This change enhances your organization’s data protection posture and supports regulatory compliance. If DLP policies are already in place for Outlook desktop or web, no additional configuration is required. The feature is on by default and requires no admin action to enable.
What you can do to prepare
What you can do to prepare
- Review existing DLP policies in Microsoft Purview to ensure they are scoped to include mobile clients.
- No new policies are required if DLP is already in use for Outlook desktop or web.
- No additional licensing is needed beyond what is already in place for Microsoft Purview DLP.
