Set Microsoft Remote Desktop 10 to view another users session
Unfortunately no.

Microsoft Remote Desktop is designed for the remote user to have their own desktop working environment and as such is not designed for screen sharing like LogMeIn or Teamviewer.

If you are looking for a free screen sharing solution or one that does not count on someone else's network infrastructure you might look into using VNC. It is common on Linux machines but as it is open source also available on Windows, Mac and a bunch of OSs you have possibly not even heard of. In fact macOS screen sharing/Remote Desktop is based on VNC.

There are a lot of versions of VNC out there I linked to the first one that came up in an internet search. There are many others.
