When a site loads in IE mode, the IE logo indicator displays on the left side of navigation bar. You can click the IE logo indicator to display additional information, as shown:

Only those sites that you specifically configure (via policy) will use IE mode, all other sites will be rendered as modern web sites. For a site to use IE mode, you need to:
Note
We only process one Enterprise Mode Site List. The Microsoft Edge site list policy takes precedence over the Internet Explorer site list policy.
The following prerequisites apply to using Microsoft Edge with IE mode.
Important

Important
** Windows 7 and Windows Server 2008 R2 will be supported by Microsoft Edge even after those operating systems go out of support. In order for IE mode to be supported on these operating systems the devices will need to have the Extended Security Updates for Windows 7. We recommend that you upgrade to a supported operating system as soon as possible in order to remain secure. Support for Microsoft Edge with the Extended Security Updates should be considered a temporary bridge to getting to a supported OS state.
