One of our faculty tried to send an email via "Navigation Block>My Mail>Compose" to his metacourse students but was given an error (see screenshot) that the "search has too many results." We noticed that in a smaller metacourse this function was available.
Question: Is there a specific enrollment number that initiates this error? At what number of enrollment are instructors no longer able to send a message to all students enrolled in a metacourse?
Thank you!
