Hello,

not sure if this can help but I found the issue might be related with Mark of The Web (MoTW).

mht/mhtml files opens without any issue if you Unblock the file:

 

 

 

You can also leave the file Blocked and set the Edge flag "#edge-internet-explorer-integration-block-with-motw" to Disabled:

 

 

I'm looking for a quick solution to apply the cfg on all Windows devices.

Maybe adding the URL to "Safe zone".

Thanks,
Andrea

Hello,

just an update.

I forgot to mention that the .mhtml file is being downloaded from our Intranet (mydomain.lan).

So I solved this by simply adding "mydomain.lan" as Intranet Zone (1) to "Site to Zone Assignment List" under "Computer Configuration", "Policies", "Administrative Templates", "Windows Components", "Internet Explorer", "Internet Control Panel", "Security Page":

 

After a GPO refresh the downloaded file no longer shows "Unblock" and the .mhtml file opens within MS Edge.

Hope this helps.
Thanks,

Andrea
