Hello juwon son,
When a user logs off or their session is forcefully disconnected, the associated session ID can be released and becomes available for use by other sessions. You could free up some session ids by
implementing session timeout policies: Path: Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host-> Session Time Limits
Adjusting session timeout policies can help in releasing session IDs more quickly. Sessions that have been inactive for a specified period can be automatically logged off.
Regards,
Karlie
