The Remote Desktop web client lets users access your organization's Remote Desktop infrastructure through a HTML5-compatible web browser such as Microsoft Edge, Internet Explorer 11, Google Chrome, Safari, or Mozilla Firefox (v55.0 and later). Test the scenario. Test the scenario with Internet Explorer on a Windows 7 or 10 computer.
Microsoft Edge is the new default web browser for Windows 10. However, if you're running Remote Desktop Web Access (RDWEB) or web apps that require ActiveX controls, the Edge browser may not work, and we recommend that you continue to use Internet Explorer 11.
As seen in the following side-by-side images, the Connect to a remote PC tab is missing from the Edge UI (the image on the left), whereas in Internet Explorer (the image on the right) this tab is still displayed.
When Internet Explorer is configured to work in this scenario, the MsRdpClientShell - MsRdpWebAccess.dll add-on is loaded as an ActiveX control.
Cause
This issue occurs because, by design, ActiveX controls are not supported in Microsoft Edge.
Resolution
Microsoft Edge is the default browser in Windows 10, with Internet Explorer provided to handle legacy sites.
If you have specific websites and apps that have compatibility issues with Microsoft Edge, you can use the Enterprise Mode site list. This lets you continue to use Microsoft Edge as your default browser while also making sure that sites and apps that rely on Internet Explorer continue to work.
To download the Enterprise Mode Site List Manager tool from the Internet Explorer Download Center, go to Enterprise Mode Site List Manager.
To add sites to your Enterprise Mode site list, see https://technet.microsoft.com/en-us/library/mt270205.aspx#fix_specific_sites.
