Question

我在同步工具中重新创建日历会议事件（使用CreateItem），基本上为会议保留了一些属性并将其写回。

但是，有些属性是只读的，我认为无法保留其状态：

IsMeeting
IsCancelled
MeetingRequestWasSent
IsOnlineMeeting

其中一些布尔值存储在属性AppointmentState中，但也是只读的：

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.

如果我设置了其他会议属性，可能会自动设置IsMeeting，例如OptionalAttendees或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Meeting request properties not settable in EWS SOAP calls?）的后续行动。

您应该能够使用MAPI扩展属性：任命状态是

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

所以应该是类似

的SOAP

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

（我使用托管API，并从跟踪日志中获取该XML，希望这是您可以使用的）

[由OP编辑]这是完成工作的完整调用：

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

  <typ:MailboxCulture>en-US</typ:MailboxCulture>
  <typ:TimeZoneContext>
     <typ:TimeZoneDefinition Id="W. Europe Standard Time"/>
  </typ:TimeZoneContext>
</soapenv:Header>
<soapenv:Body>
<mes:UpdateItem ConflictResolution="AutoResolve" SendMeetingInvitationsOrCancellations="SendOnlyToChanged">
   <mes:ItemChanges>
      <typ:ItemChange>
         <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“成功”，但报告了（一）冲突。我不知道哪一个：
