126.96.36.199.3 Sending a Meeting Update
The organizer or delegate of the organizer sends an update to inform attendees of changes to an event that has already been sent out (according to the PidLidFInvited property (section 188.8.131.52) on the Meeting object). To do so, the client creates and submits a Meeting Update object, following the same rules as sending a Meeting Request object, as specified in section 184.108.40.206.1, with differences as explained in this section.
If the value of the PidLidLocation property (section 220.127.116.11) was modified by the user on the Meeting object, the client SHOULD set the value of the PidLidOldLocation property (section 18.104.22.168) on the Meeting Update object to the old value. Similarly, if the value of the PidLidAppointmentStartWhole (section 22.214.171.124) and/or PidLidAppointmentEndWhole (section 126.96.36.199) properties were modified by the user on the Meeting object, the client SHOULD set the value of the PidLidOldWhenStartWhole (section 188.8.131.52) and PidLidOldWhenEndWhole (section 184.108.40.206) properties to the old values respectively.<50>
