Query user log

  • User log inquiry service is available for the staff (@mx), students (@oz,@m98-@m106, etc.), and departments (@my) email systems under our management as of 2017/04/21, so that users can understand the usage of their e-mail account.
  • Four types of records are currently available for inquiry, including account management records (such as: change password), failed login records, successful login records, and SMTP sending mail records.
  • Users who suspect any abnormal situations with their account may use this service to observe if there are any successful login records from unknown IP addresses to determine if their password was stolen. If your password was stolen, please change your password immediately.
