IE Mode Redirect Loop - SharePoint Online

Our SharePoint Online sites feature lots of links to our local network file system (file://), which new Edge blocks access to. (I understand the security concerns there.) Some online searching sh...

I resolved this issue.

If I had scrolled down in the IE Mode doc, I would have seen:

This is probably happening because the site you are trying to reach is redirecting to an authentication server that's not configured to open in IE mode. You can try opening the site in standalone IE11 with Developer Tools open to see the identity of the authentication server.

The solution is to configure the authentication server in your Enterprise site list as “neutral”. You can do this using the Enterprise Mode Site List Manager or directly in the sitelist XML.

I had to use developer tools (network pane) to see where the redirects were happening. For Microsoft Online, the domains I added to the Enterprise Mode Site List as neutral were:
login.microsoftonline.com
login.windows.net
<my ADFS domain> (just in case)

Hello,

I'm having the same issue. I have added the authentication sites added to the Site List as neutral. I have MFA enabled. I'm adding <mysite.sharepoint.com/sites/<subsite>/<subsite> as I do not want all my whole SharePoint sites in IE mode. I did noticed that if I log into the SharePoint in IE11 once then Edge takes me directly into my IE Mode subsite.

Any suggestions?

Thanks,
