使用EWS CreateItem操作转发电子邮件时模式验证错误

Question

当我试图使用EWS创建操作转发电子邮件时，我得到了下面的错误。

请求模式验证失败:命名空间'ForwardItem‘中的元素'http://schemas.microsoft.com/exchange/services/2006/types’在名称空间'http://schemas.microsoft.com/exchange/services/2006/types‘中具有无效的子元素'Subject’。可能需要的元素列表:名称空间“CcRecipients、BccRecipients、IsReadReceiptRequested、IsDeliveryReceiptRequested、From、ReferenceItemId、NewBodyContent”

根据这个链接，“Subject”是“ForwardItem”下的一个有效元素。我正在使用Exchange2013。对我做错了什么有什么想法吗？同样的请求适用于O365。

SOAP请求

Answer 1

ForwardItem要求元素按照模式- ForwardItem中定义的顺序排列。

尝试将Subject移动到ToRecipients之上

<t:ForwardItem>
<t:Subject>Email Submitted</t:Subject> 
<t:ToRecipients>
<t:Mailbox>                               
 <t:EmailAddress>admin@test.onmicrosoft.com</t:EmailAddress>
</t:Mailbox>
</t:ToRecipients>           
<t:ReferenceItemId Id="AQMkADJmMTI3Njk1LWZjOWItNDM2Os.."
 ChangeKey="CQAAABYAAAAmV1x/D6z5Q7lUEv1+KENlAAAAAACV"/>          
<t:NewBodyContent BodyType="Text"></t:NewBodyContent>
