18.104.22.168 Publishing Free/Busy Data
The free/busy data is published whenever appointments are created or deleted or when any of the following three properties of an appointment are modified: PidLidAppointmentStartWhole ([MS-OXOCAL] section 22.214.171.124), PidLidAppointmentEndWhole ([MS-OXOCAL] section 126.96.36.199), or PidLidBusyStatus ([MS-OXOCAL] section 188.8.131.52).
A client keeps a local copy of free/busy data and publishes the changes periodically or immediately after the data changes. A client can read or write free/busy data for another user.
The client performs the following steps to publish the data:
The client determines the data to be published by using the process specified in section 184.108.40.206.1.
If the message does not exist, the client creates a new Message object and performs step 2 to determine the subfolder and the subject of the message.
If the free/busy message was created, the client sets the third binary value of the PidTagFreeBusyEntryIds property (section 220.127.116.11) to the EntryID of the free/busy message. For details about how to create a Message object, see [MS-OXCMSG].
