Hi Sujeeva, thanks for your answer. Yes, I found the logging configuration in the Admin Panel. Unfortunately, even with logging mode 'debug' activated there's no information about fetched mails except for their number. Not enough for the forensics I was attempting :-( I should have retracted my question when I found out. Thanks for the time you invested. Susan Am 05.09.2017 um 15:20 schrieb Sujeeva Tissaarachchi:

Did you check Admin Panel-> System Administration - > System Log

Alternatively, login to server and locate to: /opt/otrs/var/log/otrs.log
