Bug description

An iMIP cancellation messages is not propagated to the personal calendar because the attendee property is not processed properly.

Steps to reproduce

  1. Tom (using Google Calendar) sends an invitation to Bob and Alice.
  2. Bob accepts the invitation via Nextcloud Mail.
  3. The event is added to Bob's calendar, and Tom’s calendar updates Bob’s attendance status.
  4. Tom deletes the event in Google Calendar.
  5. Bob receives an email, but the event is flagged with imip_message = true and imip_error = true, instead of being removed from his calendar.

Expected behavior

The event should be canceled in Bob's personal calendar.

Nextcloud Server version

master

Nextcloud Mail version

main

Additional info

$attendee = substr($vEvent->{'ATTENDEE'}->getValue(), 7);
if (strcasecmp($recipient, $attendee) !== 0) {
$this->logger->warning('Recipient must be an ATTENDEE of this event');
return false;
}

$attendee = $vEvent->{'ATTENDEE'}->getValue();
