Microsoft Edge – Catastrophic Failure

Have you ever wondered why Copilot couldn’t access, process, or return certain content?
Microsoft is making that experience much easier to understand. Previously, users could see different messages depending on how a Microsoft Purview Data Loss Prevention (DLP) policy was triggered, which sometimes made it unclear why content wasn’t available.

With this update, Microsoft 365 Copilot will now display a consistent notification whenever organisational DLP policies prevent access to content. The goal is simple: improve transparency, reduce confusion, and help users understand that Copilot is respecting their organisation’s data protection policies.

What’s Covered?

The new standardized message applies to Microsoft Purview DLP protections across Microsoft 365 Copilot and Copilot Chat, including:

Grounding DLP
Prompt DLP
External Email DLP

Where Will Users See It?

The unified notification can appear across Microsoft 365 Copilot experiences powered by Microsoft 365 Chat orchestration, including:

Microsoft 365 Copilot
Microsoft 365 Copilot Chat
Microsoft Teams Copilot experiences
Outlook on the web Copilot experiences
Microsoft Edge Copilot experiences
Other Microsoft 365 Copilot chat experiences that rely on Microsoft 365 Chat orchestration

Whenever a DLP policy restricts Copilot from using specific content, users will see the same clear message indicating that access to some content has been restricted by an organisational policy.

Rollout Timeline

The feature is now rolling out across all environments:

Worldwide: Available from July 15, 2026
GCC: Available from July 20, 2026
GCC High and DoD: Available from July 23, 2026

What This Means for Your Organisation

Organizations already using Microsoft Purview DLP with Microsoft 365 Copilot or Copilot Chat don’t need to take any action. The update does not change how DLP policies work. Instead, it improves the user experience by providing a clearer and more consistent explanation when content is blocked.

For IT administrators, this is a good opportunity to review existing training materials, user documentation, and support resources to ensure they reflect the new messaging experience.

Bottom line: the protection remains the same, but the explanation gets better. Users gain more clarity on why content is unavailable, while organisations continue to benefit from the same trusted data protection controls.

The Scareware Blocker is a New feature in Microsoft Edge designed to protect users from tech support scams, often referred to as scareware. These scams use aggressive web pages to trick users into thinking their system is infected with malware, pressuring them to call fake tech support numbers. Scareware blockers use a machine learning model to recognize the tell-tale signs of scareware scams and put users back in control of their computer.

Here’s how it works:

Machine Learning: It uses a machine learning model to detect and block scareware sites.
User Control: When a suspicious site is detected, Edge blocks it and shows a warning message, giving users the option to close the page or proceed if they believe it’s safe

“Scareware” scams are a particularly convincing type of tech support scam. They use aggressive web pages to convince victims into thinking their system is infected with malware, pressure them to call a fake tech support number, and try to gain access to the computer. Last year, Hollywood even made a blockbuster action movie with scareware scammers as the villains.

To enable Scareware Blocker in Microsoft Edge:

Open Edge and click on the three-dot menu in the toolbar.
Select Settings.

Navigate to Privacy, search, and services.
Find the Scareware Blocker option and toggle it on

When scareware blocker suspects a page is a scam, Edge will put users back in control by exiting full screen mode, stopping aggressive audio playback, warning the user, and showing a thumbnail of the page they were just viewing:
