We're introducing the ability to display a customized message or hyperlink in the toast notification shown when an Endpoint Data Loss Prevention (DLP) policy is triggered. A toast notification is a small, temporary message that appears on the user's screen when an Endpoint DLP policy is triggered. It will include the customized hyperlink you configure. This enhancement helps organizations provide clear guidance or direct users to internal resources when a policy blocks or restricts an action.

explanation for non-techies**

Microsoft Purview is introducing a new feature for Endpoint Data Loss Prevention (DLP) that allows administrators to add customized messages or hyperlinks to toast notifications. Imagine a toast notification as a digital sticky note that pops up on your computer screen when certain actions are restricted or blocked by company policies. This new feature is like being able to write a personalized note on that sticky note, guiding the user on what to do next or directing them to helpful resources.

For instance, if a user tries to send a sensitive document via email and the DLP policy blocks it, the toast notification can now include a message like, "Please refer to our data handling guidelines," with a link to the company’s internal policy page. This is similar to having a road sign that not only tells you to stop but also points you to a detour route.

This feature will be available worldwide from late December 2025 to early January 2026, and it requires the Endpoint DLP client to be updated to version 4.18.25110 or higher. It’s important for administrators to review their current DLP policies and decide if adding these customized messages or links would be beneficial for their users. This can help reduce confusion and ensure that employees have the information they need to comply with company policies.

No changes will be made to how DLP policies work; the logic and enforcement remain the same. It’s just about enhancing communication with users when a policy is triggered. This change should be communicated to your helpdesk or compliance team to ensure everyone is aware and can assist users effectively. There are no additional compliance considerations identified, but it’s always good to review and ensure alignment with your organization’s needs.
