a) meeting request arriving per mail via felamimail_activesync::GetMessage(List) b) EGw internal meeting requests via calendar_activesync::GetMeetingRequest(s) EGw backend returns both via INBOX to the client device (b) with negative id's to not conflict with mail uid's) MettingResponse method in EGw backend calls calendar or fmail depending on id Unfortunately this is NOT yet completly working: - could not test with fmail, as I have no permanent internet access - MeetingResponse method of calendar get never called, in fact client never sends one :-( - meeting requests via calendar a now displayed double: a) via calendar_activesync::GetMessage(List), which could be switched off easily b) via calendar_activesync::GetMeetingRequest(s) client sends no MeetingResponse on either of them, for a) it displays buttons to accept, tentative or decline, but only calls SendMail and ChangeMessage (without status) --> do NOT update if you already use AS!!!!!!!!!!!!!!!!!!!!!!!!!!
