We had many problems like this before understanding what is written
here: https://valentijn.sessink.nl/?p=1124
Mainly it talks about thunderbird's behaviour with invitations and mail
associated with non-personnal calendar…
Hope this can help…

Hello,
it happened for another appointment before (same user, using Thunderbird
by the way). The appointment is recurring monthly. The next occurence
would be on Thursday, 3rd of June.
The attendee received in the notification that the occurence on June (!)
5th has changed (which is in the past). He received that on Monday, 23rd
of June at 14:01 PM.
In the logs I see ("user123" is the guy who owns the appointment, using
T-Bird).
The “c_name” of the appointment would be
237F41-681C8700-27-1DA00BE0.ics

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.

*Subject:* [SOGo] Strange calendar notifications
Hello all,
we have faced a strange issue with SOGos calendar notifications. 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
