I have successfully set up a group policy which means the external websites I list in a sitelist.xml file will automatically load in IE mode, but this does not work for URLs which start file:///
I thought I might be able to force the load via a shortcut of the format:
"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --new-window --ie-mode-file-url "C:\TestSoftwareSuite\index.htm"
but this does not work. It does open a new Edge window (so the flag --new-window works) and the page loads, but in nornal Edge mode. The flag --ie-mode-file-url, which is referenced in https://docs.microsoft.com/en-us/deployedge/edge-ie-mode-add-guidance-filetype-associations (althought there are only three Googe results fo a search for "--ie-mode-file-url"!), does not apear do do anything.
I have also tried it with with external site as follows:
"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --new-window --ie-mode-file-url "bbc.co.uk"
and again it is niot working.
Is there actually any support for --ie-mode-file-url in Edge?
I am using Edge 88.0.705.81 (Official build) (64-bit)
