There seems to be a problem with Meeting Requests not issued by the current user.
If a client like Outlook tries to change StartTime or EndTime, the request gets
accepted with Status 1, but the Meeting date is not changed, as it is readonly.
The webinterface reflects this and doesn't let the used edit the Meeting, but when
such an EAS request comes to SOGO, it replies with <Status>1</Status>.
This leads to Outlook on that very machine, that does the request, moving the
meeting date, but all other machines don't leving the calendar in an inconsistent state.
On such errors, I think the correct response status should be status 7 
(Conflict matching the client and server object)
See: https://learn.microsoft.com/en-us/openspecs/exchange_server_protocols/ms-ascmd/08151746-faf7-40a3-832b-b42e88a0b729
Attached you will find a log of such a case.
My guess is that processSyncChangeCommand logic is flawed. I can see the following logic:

                    // Don't update the component without proper permission
                    if ([roles containsObject: SOGoCalendarRole_ComponentResponder] || [[sogoObject ownerInContext: context] isEqualToString: [[context active
User] login]])
                      {
                        [o changeParticipationStatus: allChanges  inContext: context  component: sogoObject];

                        if ([syncCache objectForKey: serverId])
                          [syncCache setObject: [NSString stringWithFormat: @"%f", [[sogoObject lastModified] timeIntervalSince1970]]  forKey: serverId];
                      }
                    // Trigger a change-command to override client changes since we don't have permissions
                    else
                      [sogoObject touch];


It can be seen in the log that indeed the requestor gets an update where it moves the
element back to its original position, but Outlook doesn't seem to like that.
Why was it implemented this way? IT seems to cause problems and may not be EAS compliant.
