Introduction

We’re updating Microsoft Purview Endpoint Data Loss Prevention (DLP) to display the currently signed-in user’s email address for Windows devices on the device onboarding page. This change aligns the Windows experience with macOS and responds to admin feedback requesting faster ways to confirm device ownership and troubleshoot onboarding or policy issues. By surfacing the logged-in user alongside existing device insights, admins can more quickly validate device context without additional investigation.

When this will happen:

• Public Preview: Rolling out in late February 2026 and expected to complete by mid-March 2026
• General Availability (Worldwide): Rolling out in late March 2026 and expected to complete by mid-April 2026

How this affects your organization:

Who is affected:

• Microsoft 365 administrators managing Microsoft Purview Endpoint DLP
• Organizations with Windows devices onboarded to Purview

What will happen:

• Admins will see the email address of the currently signed-in user for Windows devices.
• The user email appears on the Device details page in Purview → Settings → Device onboarding.
• This information is displayed alongside existing device insights.
• The feature is enabled by default.
• There is no impact to users and no change to DLP policy behavior or enforcement.

What you can do to prepare:

No action is required.

Optional steps you may consider:

• Inform helpdesk or security teams that logged-in user information is now visible for Windows devices.
• Update internal documentation or troubleshooting guides that reference Purview device onboarding.
• Review device visibility in Purview to ensure appropriate admin access controls are in place.

Compliance considerations:

No compliance considerations identified, review as appropriate for your organization.

[Introduction]

Microsoft is enhancing Microsoft 365 Copilot by allowing users to search for, select, and insert SharePoint Lists directly into their prompts in Copilot Chat to ground their conversations. When writing Copilot prompts in the chat box, users will be able to search for and select SharePoint Lists from Context IQ by either typing forward slash “/” or selecting Add work content from the Plus menu (+). This helps ground prompts in contextually relevant data, improving the accuracy and usefulness of Copilot responses.

This message is associated with Microsoft 365 Roadmap ID 422308.

[When this will happen:]

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

• No impact to tenant admins or existing configurations.
