My user bumped into the "Unsual sending activity" message "550.5.4.6" I went to the control panel and try to see the Audit logs to see what was happening and the page stays like this: https://drive.google.com/file/d/1XPpfbeSnQYQurN20hC2st2fu0SZ1rmLj/view?usp=drivesdk and therefore i couldn't see how many messages were sent by the user.
