Question

EWS文档说，要发送邮件并将副本保存到已发送邮件文件夹，您应该use the CreateItem operation with a MessageDisposition value of SendAndSaveCopy。

   <m:CreateItem MessageDisposition="SendAndSaveCopy">
     <m:SavedItemFolderId>
       <t:DistinguishedFolderId Id="sentitems" />
     </m:SavedItemFolderId>
     <m:Items>
       <t:Message>
         <t:Subject>Company Soccer Team</t:Subject>
         <t:Body BodyType="HTML">Are you interested in joining?</t:Body>
         <t:ToRecipients>
           <t:Mailbox>
             <t:EmailAddress>sadie@contoso.com </t:EmailAddress>
           </t:Mailbox>
         </t:ToRecipients>
       </t:Message>
     </m:Items>
   </m:CreateItem>

成功时，“服务器使用CreateItemResponse消息响应CreateItem请求，该消息包含ResponseError的NoError，表示电子邮件已成功创建，以及新创建的消息的ItemId。”

对Office 365使用EWS，几乎成功运行。邮件已发送，副本将保存到已发送邮件...但已保存副本的ItemId在响应中返回不：

   <m:CreateItemResponse>
     <m:ResponseMessages>
       <m:CreateItemResponseMessage ResponseClass="Success">
         <m:ResponseCode>NoError</m:ResponseCode>
         <m:Items />
       </m:CreateItemResponseMessage>
     </m:ResponseMessages>
   </m:CreateItemResponse>

有没有办法指示EWS服务器实际返回已保存副本的ItemId？或者，一旦发送完成，找到保存的副本的首选机制是什么？

显然，文档错误或不适用。 This MSDN blog post符合我的经验：没有从SendAndSaveCopy CreateItem请求返回ItemId。它表明了以下内容：

Simply stamp your e-mail message with a custom extended property when you create the message, and then use that extended property to find the message in the Sent Items folder after it has been sent.

评论者建议，您应该执行以下操作，而不是使用昂贵的FindItems - with-SearchFilter调用来查找自定义属性标记的已保存副本，而应执行以下操作：

1. Set your extended prop.

2. Do a FindItem with NO restriction against the sent items folder, SORTED by creation date descending with a indexed page view of about 5. Include your extended prop in the PropertySet.

3. Iterate across the results looking for your extended prop.
