Summary	0002757: Wrong attendee status is synced (PARTSTAT)
Description	Hello, we have the problem that sometimes the "PARTSTAT" of an "ATTENDEE" gets overwritten. And with this every attendee gets a mail, that the event has changed. This can not always be reproduced. But I noticed that if an attendee changes his PARTSTAT (by accepting the event) the "LAST-MODIFIED" of the event is not updated. So I suspected that the client only checks this and overwrites the event sometimes. First I thought this is an iOS problem: https://discussions.apple.com/message/25624105#25624105: And I reproduced this problem with it. But I am not able to do this anymore. And this happens irregularly. Very strange behavior. So is it correct to not update the "LAST-MODIFIED" entry of an event when an attendee accepts the event? And if not could you please change this? Thanks a lot!
Steps To Reproduce	create event with alarm and one or more attendee sync with client let one attendee accept the event don't sync before the alarm triggers wait for the alarm accept the alarm

Were only a few users. But this happens from time to time. And I would suspect that SOGo is used in much larger environment with a little bit more than 10 calendar users.
