Adaptive state detection can be provided for conferencing solutions. A monitoring service can be executed on the computing system employed by each participant to access a conference. The monitoring service on a presenter computing system can detect when the presenter has commenced sharing his/her screen or application and can identify a schema for performing state detection. The monitoring service shares the schema with the monitoring services on the listener computing systems. As the screen content is shared, the monitoring services can implement the schema to cause state notifications to be provided to the monitoring service on the presenter computing system. The state notifications can represent whether the listener computing systems are receiving the shared screen content and/or to what extent the shared screen content is delayed.
