Background

Internet Explorer 11 and Microsoft Edge supports two browsing experiences: Internet Explorer in the Windows UI and Internet Explorer for the desktop. Although both use the same underlying technology to render web applications, the behavior and experience might differ. For example, Internet Explorer in the Windows UI has limited Adobe Flash support, and it does not support other plug-ins, such as Java applets. Web applications that rely on these technologies may fail to deliver expected content in Internet Explorer 11 and Microsoft Edge in the Windows UI.

Resolution

The web application should be re-engineered by moving to standards-based technologies (including supported HTML5 features) in order to function correctly in Internet Explorer 11 and Microsoft Edge in the Windows UI.
