Problems with Enterprise Mode (IE Mode) in recent builds ?

We are using the Enterprise Mode Site List to open specific internal pages using the IE rendering engine. (Primarily for our ERP app which requires Java Web Start... Not supported under Chrome / Chromium.... )

 

This has been working perfectly almost two years. We were using it before Edge Chromium, and now too with Edge Chromium..... Until recently, this has worked very well.

 

In the past few weeks, the experience of opening pages in IE mode has become inconsistent. Sometimes the page will open in IE mode, sometimes the page will open in a standard Edge Chromium tab... If I look at the config in edge://compat/enterprise ... All the expected pages are listed with Engine IE11 mode listed (and the XML version number is current)... So obviously the browser is downloading the Enterprise Mode XML file from our internal web server without issue...

 

This all seems to have started with Version 86.0.622.38 ... And still seems to be happening in .48 too (the latest release build).  Often times opening a new Edge session will cause the IE Mode sites to open correctly in IE mode again.    Also, using the compat/enterprise "Force Update" button will also cause the session to work correctly again.  (But the SiteList has not changed in more than 6 weeks.)

 

Is there anything I can do to troubleshoot why Edge is not opening the designated pages, using the correct mode?

    jpochedley Hi Joe - Thanks for reaching out!  I just talked to the IE Mode team and we've had a few other reports from customers with very similar issues all starting around V86.  We've been trying to investigate but I don't think we've been able to get a consistent repro.  

     

    It would be very helpful to get your logs, repro steps, traces and other information we can use to troubleshoot.  Would you be able to file a customer support request?  They should be able to work with you to gather the necessary information for our team.  Thanks for your help!

      Unfortunately I cannot repro the issue reliably myself. It seems to happen intermittently. This far i have not been able to figure out a set of actions that can make the problem happen consistently.

      Let me know what logs I can collect which can help troubleshoot the issue.

      I do not know whether I can open a paid support request, or whether we have available VL support requests. I will need to check with the team.

        Hi jpochedley, Kelly_Y directed me to your post as we just started seeing the same issue.  My full post is here:
        Edge Beta intermittently ignoring IE Mode - Microsoft Tech Community

        I can reproduce the issue randomly if I keep loading the same site on new tabs in Edge Beta or Edge Stable.  The key is I have to keep opening a new tab and paste the site in the address bar and just keep doing so until one fails.  So Kelly_Y  if you could let me know which types of logs or traces you need, I can start working on those.  Do you have any documentation on that?  Thanks!
