A student in the Santa Monica–Malibu Unified School District accessed the school's email.
The student was able to send messages to the student body for 16 minutes before the district’s technology team discovered the mass emails and disabled the system.
The Gmail application was been temporarily disabled, but teachers were able to use private comments within Google Docs Assignments or use the Stream within Google Classroom for public comments.
