3 years ago i have posted about enabling Enterprise Mode in Microsoft browsers, when we were migrating to IE11 on my previous job. It helped a lot as we still needed to open a few sites with older IE version. There was also an option to make sites open in Edge instead (or if you open a site in Edge, to redirect to IE). To make it work you had to add a few registry entries and store an xml file with URLs and settings somewhere for browsers to read. Currently we are moving to Chromium Edge in our environment (as Legacy Edge soon will stop being supported) and we want to make it easier for our users to use this new browser enabling them to reach legacy systems and sites. There were a few changes and improvements in Enterpise Mode regarding Edge since my last post that i wanted to share.
In our organization we always had (and probably will) a few internal and external systems, which are working best with Internet Explorer. Better yet, with IE9. Actually it is even more complicated as we also had to enable Compatibility Mode for some sites via Group Policy for them to actually work properly with IE9 (i guess they were designed to work with IE7 or such..). While evaluating upgrade to IE11 we have found out, that in many cases standard IE11 won’t work. I have read before about the upcoming Enterprise Mode feature (if i remember correctly, it was enabled with an update in August of 2015, so if you install clean IE11 upgrade, it won’t have it until you install all the later updates from Windows Update or WSUS). So, after a lot of testing and trial i have made all our systems work with IE11 (well, almost, some of them still have minor issues). And i will share my findings here.
