Exchange EWS not returning message body for calendar

问题

So i'm trying to fetch all the calendar event from office360.com . I am using ews to get the data. I sent a request of

    <?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
               xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
  <soap:Body>
    <FindItem xmlns="http://schemas.microsoft.com/exchange/services/2006/messages"
               xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"
              Traversal="Shallow">
      <ItemShape>
        <t:BaseShape>AllProperties</t:BaseShape>
        <t:BodyType>HTML</t:BodyType>
      </ItemShape>
      <ParentFolderIds>
        <t:DistinguishedFolderId Id="calendar"/>
      </ParentFolderIds>
    </FindItem>
  </soap:Body>
</soap:Envelope>

This soap request xml is not returning me the calendar message body but i get the subject and other data . What am i doing wrong here ? any help is appreciated.

回答1:

The body needs to be retrieved in a separate call.

Or you can load the property first.

The second is easier but you need to define all properties you want back and if it is a lot, it can be a pain.
