How to send messages with msg.exe?

Question

Access rights

Windows Server 2012 is in a workgroup.
A terminal server is deployed on it.
It is necessary to enable the user (without admin rights) to send messages to all users connected to the terminal server.
Googled, found that you can run the msg.exe program from the console.
The program works, but the message does not reach users. (no rights)
How to allow sending user messages (without admin rights) through the msg.exe program to all users?
