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

We will communicate via Message center when we are ready to proceed.

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.

Introduction

Surveys Agent is a new Copilot agent in Microsoft 365 that helps users build, run, and analyze surveys with ease. It streamlines the entire survey lifecycle—from creation to analysis—enabling faster, insight-driven decisions with less manual effort.

When this will happen

• Public Preview (Frontier): Beginning mid-August 2025
• General Availability (Worldwide): Rollout is expected to begin in mid-October 2025 (previously late September) and complete by late November 2025 (previously early October).

How this affects your organization

Surveys Agent enables users to create and manage surveys directly through chat in Microsoft 365 Copilot. It simplifies survey creation, distribution, and analysis, reducing time spent on manual tasks. Surveys are powered by Microsoft Forms and adhere to existing admin policies for the Forms service.

This feature is off by default. Users can choose to install the agent from the Microsoft 365 Copilot Agent Store under the “Built by Microsoft” section.

What you can do to prepare

To ensure users can access Surveys Agent in the Frontier preview program, admins can take the following steps:

• Verify users or user groups have a Microsoft 365 Copilot license.
• Ensure the setting “Allow the following users access to Copilot agents” is configured.
• Ensure the tenant-level setting “Let users access Microsoft apps” is configured.
• (Recommended/optional) Deploy Surveys Agent automatically to users or groups via the Deploy action in Integrated Apps.

Surveys Agent creates surveys via Microsoft Forms. Admins should review Microsoft Forms policies to ensure they align with organizational standards.

Once installed, users can:
