Announcement

• Root certificate store update. Microsoft Edge’s root store is provided by the Microsoft Trusted Root Program. A recent update makes certificates no longer trusted by default if they validate to one of the listed Entrust root certificates and the certificate’s earliest Signed Certificate Timestamp (SCT) is dated after April 16, 2025 7:00:00 AM UTC. Enterprises running a website that uses an impacted certificate should acquire and deploy a new certificate not impacted by this change before that date. Alternatively, enterprises can override the constraint by installing the applicable root certificate as a locally-trusted root with the operating system; enterprises pursuing this option should carefully evaluate the risk of doing so.

Feature updates

• Removal of “Add account” option in Profile menu for Entra ID users. The option to add a linked personal account directly from Edge is no longer available in the Edge profile menu. The LinkedAccountEnabled policy is also obsolete in Microsoft Edge version 134.
• Microsoft Search in Bing deprecation and policy updates. Microsoft Search in Bing, the work search experience available on Bing.com, will be retired, such that the last day of availability is on March 31, 2025. The AddressBarMicrosoftSearchInBingProviderEnabled policy, used to configure Microsoft Search in Bing results in the Edge for Business address bar, will be deprecated and obsoleted (non-functional) in a future Microsoft Edge version. The new policy to replace this is AddressBarWorkSearchResultsEnabled which is available in Microsoft Edge version 134.
• Edge on macOS now seamlessly opens links in Teams. When Microsoft Edge is configured as the browser to open web links in Teams, then links in Teams chat will be opened through Edge, and Edge launches in the profile that matches with the authenticated profile, users can benefit from a seamless browsing experience that integrates their identity and user data across Microsoft apps. Administrators can control the availability of this feature using the "Choose Which Browser Opens Web Links" Microsoft 365 policy.
• Scareware blocker policy. Scareware blocker in Microsoft Edge is your AI powered shield designed to protect you and your users from scareware attacks. Scareware blocker is currently in preview and admins can control availability to this feature using the ScarewareBlockerProtectionEnabled Policy. For more information, see Stand up to scareware with scareware blocker, now available in preview in Microsoft Edge - Microsoft Edge Blog.
• Edge Settings Improvements. Edge Settings is migrating to WebUI2 to boost page responsiveness and introducing a series of minor visual and content upgrades to improve overall usability and utility. This includes optimizing for concise wording of individual settings, simplifying the number of pages and reorganizing content, and creating a cohesive user interface. Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
