Microsoft Edge (based on Chromium) no longer has a built-in "Trusted Sites" list like the older Internet Explorer. Instead, Edge respects the security zone settings configured in Internet Options (a legacy part of Windows). To add trusted sites for Edge, you must use the Internet Properties control panel.
Can I add wildcards like *.example.com ? A: Yes. Enter *.example.com in the "Add this website" field.
I see an error “A policy is preventing you from adding this site.” A: Your organization or Windows security settings may restrict this. Check with your IT admin or local Group Policies. By following Method 1 , you can successfully add trusted sites that Microsoft Edge will recognize, especially for features like automatic login, ActiveX (if enabled), or relaxed security restrictions on internal sites.
