Web filter blocking content in Microsoft Edge

Question

Web filter blocking content in Microsoft Edge

Mateusz Gupta 0

Hi Team,

Can you please explain me why when I blocked in my Tenant Allow/Block list in M365 for example the url "ww.onet.pl" it also blocked the website for entire company in microsoft edge browser which was desired, but now it doesn't work anymore for manually entered blocked url into edge browser? I understand that this list is for EOP, but it did block also for manually url entries. Now it doesn't block anymore. Any ideas what could change?

Hi @Mateusz Gupta ,

May I know if you have tried the group policy to block websites?

Like I mentioned I used tenant allow/block list from m365 security. We also used IoC to allow/block, but I can tell you that this option doesn't work right now aswell.

Hi @Mateusz Gupta ,

I'm not quite sure about how IoC will affect Microsoft Edge as it belongs to Microsoft Defender for Endpoint, but you can give Edge group policy a try since it is recommended for browser management. If you are wondering why IoC or Tenant allow/block list don't work, I suggest you contact Microsoft Defender support for more information. Please note that Microsoft Defender is not supported here on Microsoft Q&A.

Hi @Mateusz Gupta ,

Please note that Tenant Allow/Block List is not designed for Microsoft Edge as you have already known, so it is not expected to block websites on Microsoft Edge.

If you need to block websites on Microsoft Edge for users, please use URLBlocklist group policy. If you prefer M365 Admin Center for management, you can follow The Microsoft Edge management service tutorial and search for URLBlocklist policy in Admin Center. If successfully configured, specified websites will be blocked for your users as you would expect.
