microsoft edge secure network this setting is turned off for managed browsers

Hi Hao,

This is April, I'll be happy to assist you. Sorry to hear that you're having issue with Office 365 mail. Let me help you out.

Based on the description of the issue you provided, in Microsoft Edge, the Secure Network setting is disabled with the message that the browser is managed.

Can you confirm whether your device is connected to a work or school account, or if any group policy or third-party privacy tool has been applied that might cause Edge to show as managed?

When Microsoft Edge shows "Secure Network" or "Secure DNS" as disabled with the message "This setting is turned off for managed browsers," it typically means Edge is detecting Group Policy entries or leftover registry settings and assumes the browser is managed by an organization. Simply resetting Edge won't fix this. You'll need to clear those policy remnants from the registry and verify that there are no lingering work or school accounts still connected.

Here's step-by-step Fix that you can try:

1. Check Registry Keys
   • Open Registry Editor and navigate to the following paths:
     • HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge
     • HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Edge
     If the Edge folder exists, right-click it and select Delete If the folder isn't present (as in your case), proceed to the next step.
2. Check for Policy Flags The "manage" status can also be triggered by other policy entries. Check these locations:
   • HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft
   • HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft
   • Look for subkeys such as Policies, Management or anything referencing Edge. If found., delete them.
3. Remove Work or School Accounts
   • Go to Settings > Accounts > Access work or school
   • Disconnect any linked work or school accounts.
   • Restart your PC.
4. Reset Edge Policies Open Command Prompt (Run as Administrator and run the following command: rd /s /q "%WinDir%\System32\GroupPolicy" gpupdate /force This will clear any locally applied group policies.
5. Verify in Edge
   • Open Microsoft Edge
   • Go to Settings > Privacy, search and services > Security
   • Confirm that the Secure Network / Secure DNS toggle is now available.

Be cautious when deleting registry keys and remove only Edge-specific policy entries. If you've used third-party privacy or hardening tools, they may reapply these policies, so disable or reset them first. If your PC is genuinely managed by an organization, these settings can't be overridden.

I hope this helps. If you need further assistance you can reply to this message.

Thank you,

April P.
