What happens when a survey expiration date passes?

When a survey expiration date passes, participants who are still engaged in completing the survey will be unable to submit their responses and will effectively be exited from the survey. This means that if they have not finished their responses by the time the expiration occurs, they will be "kicked out," and their incomplete responses will not be saved. This feature ensures that the data collected within the survey is only from those participants who have completed the survey within the designated timeframe, maintaining the integrity and relevance of time-sensitive data collection.

The other scenarios imply ongoing access or submissions, which do not align with the functionality of surveys in Qualtrics once the expiration date has been reached.
