如何'set' read-only日历约会属性（与会议相关）？

Question

我正在同步工具中重新创建日历会议事件（使用 CreateItem），主要是为会议保留一些属性并将它们写回。

但是，有些属性是 read-only，我看不出有什么办法可以保留它们的状态：

IsMeeting
IsCancelled
MeetingRequestWasSent
IsOnlineMeeting

其中一些布尔值存储在属性 AppointmentState 中，但那也是 read-only：

Name      Bit      Description

None      0x0000   No flags have been set. This is only used for an appointment that does not include attendees.
Meeting   0x0001   This appointment is a meeting.
Received  0x0002   This appointment has been received.
Canceled  0x0004   This appointment has been canceled.

如果我设置其他 meeting-properties，是否可能会自动设置 IsMeeting，例如OptionalAttendees 还是 RequiredAttendees？这将有助于四个中的一个，if 我知道哪些属性会触发 IsMeeting 的设置。

（是的，这是 follow-up 到 Meeting request properties not settable in EWS SOAP calls?）。

Answer 1

您应该可以使用 MAPI 扩展属性：预约状态为

Named Prop Name: id: 0x8217=33303 = PidLidAppointmentStateFlags, dispidApptStateFlags
Named Prop Guid: {00062002-0000-0000-C000-000000000046} = PSETID_Appointment

SOAP 应该是这样的

<t:ExtendedProperty>
  <t:ExtendedFieldURI DistinguishedPropertySetId="Appointment" PropertyId="33303" PropertyType="Integer" />
   <t:Value>1</t:Value>
</t:ExtendedProperty>

（我为此使用了托管 API，并从跟踪日志中得到了 XML，希望您可以使用它）

[由 OP 编辑]这是完成任务的完整调用：

<soapenv:Envelope
  xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:typ="http://schemas.microsoft.com/exchange/services/2006/types"

     <typ:TimeZoneDefinition Id="W. Europe Standard Time"/>
  </typ:TimeZoneContext>
</soapenv:Header>
<soapenv:Body>

         <typ:ItemId <t:ItemId Id="AAMkA[snip]xAAA=" ChangeKey="Dw[snip]Mar"/>
         <typ:Updates>
            <typ:SetItemField>
               <typ:ExtendedFieldURI DistinguishedPropertySetId="Appointment" PropertyId="33303" PropertyType="Integer"/>
               <typ:CalendarItem>
                  <typ:ExtendedProperty>
                     <typ:ExtendedFieldURI DistinguishedPropertySetId="Appointment" PropertyId="33303" PropertyType="Integer"/>
                     <typ:Value>5</typ:Value>
                  </typ:ExtendedProperty>
               </typ:CalendarItem>
            </typ:SetItemField>
         </typ:Updates>
      </typ:ItemChange>
   </mes:ItemChanges>
</mes:UpdateItem>
</soapenv:Body>
</soapenv:Envelope>

奇怪的是，结果显示 "Success"，但报告有（一个）冲突。我不知道是哪一个：

         </m:ResponseMessages>
      </m:UpdateItemResponse>
