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
Andrea,
thanks for getting back to me on this. i followed your instructions to the letter but "unblock" still appears on the properties page of my mht files. now, when i click the unblock checkbox and then open the file in edge, it works but that would have to be done on every individual file which is sort of a pain in the butt. I tried to figure out what you meant about setting the Edge flag to disabled but I don't seem to have the Experiments option in my Edge settings (at least i can't find that option anywhere). Any suggestions as to where i might locate it?
i would like to mark this a "solution" but i no longer see that option. only the Reply button. Has that been removed?
Andrea,
i found the Experiments area under settings (i was clicking on the wrong gear icon). but mine do not look anything like what you show in your example above. mine look like the screenshot below and I see nothing related to mark of the web (MOTW).
