Announcements

• Important update regarding the rollout of the auto-open feature. We identified an issue with the initial implementation of the Auto-Open feature as it didn't fully respect user preferences and some settings weren't honored as intended.

  To address, the changes are being rolled back in phases during the next month to ensure that all user preferences are correctly honored. As a result, users temporarily notice a return to previous behavior where the sidepane opens even if the sidebar visibility is set to "Off".

  Here are a few ways to manage the auto-open experience:

  • Manually Turn Off Auto-Open Pane: Users can manually disable the Auto-Open experience by navigating to the settings page if they prefer not to see the sidepane open for Outlook and Teams links.

  • Automatic Engagement-Based Logic: If a user doesn't engage with the auto-open experience and quickly closes it three times in a row, the feature is automatically turned off.

  • Turn off Auto-Open Pane using admin policies: Admins can control the Auto-Open experience by using either of these policies.

    • HubsSidebarEnabled: Set as "False" to turn off
    • ExtensionSettings: Set the sidebar_auto_open_blocked flag as "True" to turn off

Feature updates

• Configuration Update for MIP Enforcement. With Microsoft Edge 142, new configuration step introduced to maintain MIP protections via Microsoft Edge management service. Existing settings remain active until admins choose to update. For more information, see Protect Office documents with Microsoft Purview Information Protection labeling.

• SmartScreen and Scareware Blocker. In organizations where both Scareware Blocker and SmartScreen are enabled, users now can send signals to SmartScreen. The new setting “Share detected scam sites with Microsoft Defender SmartScreen” is available under edge://settings/privacy/security. If enabled, Scareware Blocker reports its verdict to Microsoft Defender SmartScreen to enhance protection. Admins can control availability to this feature using the ScarewareBlockerSendDetectedSitesToSmartScreenEnabled policy.

• Drag to group tabs. Tab groupings can be made by dragging a tab over another. This feature is controls the "Drag to group tabs" toggle in Microsoft Edge Settings edge://settings/appearance/tabs.

• Open external links in another profile when recommended by external applications. When Microsoft Edge is set as the default browser to open external links from applications, Microsoft Edge must determine which profile to open the links. Users can control which profile to use through the “Default profile for external links” setting. Applications such as Microsoft Teams or Outlook can also recommend a profile for the links. Currently, the user setting is prioritized over application recommendations. With this link feature, the application recommended profile is given priority, instead of the profile selected in the setting. Admins can control the availability of the feature using the EdgeOpenExternalLinksWithAppSpecifiedProfile policy.

• Tab Search. Tab Search helps users stay organized by letting them quickly find and reopen recently closed tabs or search across all open ones in a single view. From the same menu, they can also enable Vertical Tabs, access the AI-powered Organize Tabs feature, and open Workspaces.

• Desktop Visual Search. Quickly send images to Bing Visual Search from the Microsoft Edge Desktop Search Bar, identify images, people, animals, and shows; extract, copy, and translate text while keeping its format. Solve questions quickly in various subjects, get trusted information and boost your knowledge. Discover products, fashion, recipes, identify a location and more. Available on Windows devices. Admins can control availability to this feature using the VisualSearchEnabled policy. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

The Passwords and Autofill form data toggles are removed from the Settings page. Manual deletion of Passwords and Autofill remains possible via the "Delete browsing data" settings.

Rollout begins October 2025 and continues over the next few months. This change enhances performance, accessibility, and compatibility, and introduces exclusive enterprise features.

For more information, see the FAQ page.

• Local Network Access. Local Network Access in Microsoft Edge is a security feature that restricts a website’s ability to send requests to servers on your local network. When a website tries to connect, Microsoft Edge shows a prompt asking you to grant or deny permission. Protects privacy and security while maintaining compatibility with modern web standards. The ability of a website to request this permission from users is restricted to secure contexts. This feature is currently disabled by default in Microsoft Edge, but the default state may change as soon as Microsoft Edge 142. Enterprise administrators can configure Local Network Access policies. More information for users and administrators can be found here: Control a website’s access to the local network in Microsoft Edge.

Scareware blocker is enabled by default only on devices with more than 2GB of RAM and at least five processor cores. Devices that don't meet these minimum system requirements requires manual activation or may not support this feature. Admins can control availability to this feature using the ScarewareBlockerProtectionEnabled policy.

• Tab Groups – Auto-Save and Easy Revisit. Microsoft Edge now automatically saves tab groups, making it easier than ever for users to pick up where they left off. Organized tab groups are preserved and ready to revisit anytime, whether a user is switching tasks or restarting the browser. Admins can control the availability of the feature using the SyncTypesListDisabled policy with the “openTabs” data type.

• HTTPS-first mode. HTTPS-first mode in Microsoft Edge automatically upgrades HTTP connections to HTTPS when possible. If a site doesn’t support HTTPS, Microsoft Edge shows a warning to highlight the security risk. This appears only for public sites—not private ones or manually entered HTTP URLs. Users can enable the warning in edge://settings and admins can control availability to this feature using the HttpsOnlyMode policy.

• Third-party storage partitioning policy updates. The ThirdPartyStoragePartitioningBlockedForOrigins and DefaultThirdPartyStoragePartitioningSetting policies are deprecated in Microsoft Edge version 140 and planned to be obsoleted in Microsoft Edge version 145. Replacement for these policies is usage of the requestStorageAccess method. For more information, see Document: requestStorageAccess() method - Web APIs.

• Enhancement to Edge updates. Microsoft is introducing an improvement to the Settings and more menu (“…” on the menu bar) which makes it easier for users to discover when a browser update is available.

• Improved Navigation to Extension Surfaces. To improve visibility and discoverability, Microsoft Edge is introducing two navigation improvements for extensions. First, if a user has at least one enabled extension, the puzzle icon is persistent on the toolbar. Second, from the Settings and more menu, the Extensions option allows users to reach edge://extensions and the Microsoft Edge Add-ons Store directly. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Updated Collected Cookies dialog to improve performance. The Collected Cookies dialog is rewritten to improve page responsiveness. Customer-facing functionality and UX from previous releases remain the same.

• Reset Microsoft Edge enterprise sync. For users having problems syncing browsing data across other signed-in devices, they can reset sync data from the Microsoft servers via Microsoft Edge Settings edge://settings/profiles/sync/reset. This option should only be used if the sync data is available on one of the user's devices or if they want to delete all sync data from the servers. Note: In Microsoft Edge 139, reset sync is enabled for users encountering a "No permissions" MIP error and in Microsoft Edge 140, reset sync is enabled for users encountering a "Service disabled" MIP error.

• Update to Microsoft AutoUpdate policy. The MAUEnabled policy allowed admins to continue using Microsoft AutoUpdate on macOS. Since Microsoft Edge now uses EdgeUpdate, the MAUEnabled policy is obsoleted in Microsoft Edge version 140.

• Create AI generated videos with Bing. Bing Video Creator empowers users to generate AI-driven videos using text prompts, using Sora technology to bring ideas to life with ease and creativity. Available exclusively to personal Microsoft Account holders, it offers both free and fast creation modes—enhanced by Microsoft Rewards points—for producing high-quality, short-form videos directly within Bing. For more information, see Bing Video Creator | Microsoft Bing.
