Microsoft Edge has recently released a Redirection experience. This means if you are on Microsoft Edge version 87 or later, will automatically load some websites in Edge instead of Internet Explorer.
Once you disable this feature, you’ll be able to open incompatible websites in Internet Explorer, and Microsoft Edge will stop automatically opening them.
Product: v11
Module: MOBO
Step-by-step guide
Open Microsoft Edge > Elipsee icon > Settings
