Hello, This just for this specific appointment? How often the attendee received the notifications? Does the user use caldav?
SOGo don’t send event notifications on itself, a request must have been done. If you know your user and this happens often, you could try to add those logs SOGoDebugRequests = YES; -> log http request received SMTPDebugEnabled = YES; -> log smtp communication And then see if smtp is triggers after a request from this user (use the pid of the worker at the start of the log line to find which request it comes from) Without knowing more, I would guess this is a caldav problem: the client sends a caldav request to sogo that somehow thinks the event has been changed.

A user reported attendees for one of his periodic appointments got notification mails for an appointment, claiming something has changed, but the reason for the change is empty. Something like: Folgendes wurde am Termin “Test-Termin” geändert: Bitte akzeptieren Sie diese Änderungen oder lehnen Sie diese ab (German for “The following has been changed for appointment ‘Test-Termin’:") ("Please accept these changes or decline them") (There is nothing after the colon). The attendees then have the options to “Decline”, “accept temporarily” or “delegate”. Does anybody have a clue how to debug WHY SOGo is thinking there has been a change? According to the user “nothing” has been changed (which is also implied by the notification mail). Also, said user deleted this appointmnet and all occurences, and created it anew - issue still persists. Thanks and best regards, Alex --
