EWS returns a Success response code even if a batch deletion request isn't completed in Exchange Server 2013

When you issue a batch request from Exchange Web Services to delete some items, the deletion operation can't be completed within one minute in Microsoft Exchange Server 2013, and you receive a Success response code instead of a Time-Out code even though the operation isn't completed. The incorrect response code that says Success looks something like this:

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
  <h:ServerVersionInfo MajorVersion="15" MinorVersion="1" MajorBuildNumber="184" MinorBuildNumber="17" Version="V2_43" xmlns:h="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" />
  </s:Header>
  <s:Body>
  <m:DeleteItemResponse xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
  <m:ResponseMessages>
  <m:DeleteItemResponseMessage ResponseClass="Success">
  <m:ResponseCode>NoError</m:ResponseCode>
  </m:DeleteItemResponseMessage>
  <m:DeleteItemResponseMessage ResponseClass="Success">
  <m:ResponseCode>NoError</m:ResponseCode>
  </m:DeleteItemResponseMessage>
[...]
  <m:DeleteItemResponseMessage ResponseClass="Success">
  <m:ResponseCode>NoError</m:ResponseCode>
  </m:DeleteItemResponseMessage>
  <m:DeleteItemResponseMessage ResponseClass="Success">
  <m:ResponseCode>NoError</m:ResponseCode>
  </m:DeleteItemResponseMessage>
  </m:ResponseMessages>
  </m:DeleteItemResponse>
  </s:Body>
</s:Envelope> 

However, the expected response code should be as follows:

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
  <h:ServerVersionInfo MajorVersion="15" MinorVersion="1" MajorBuildNumber="184" MinorBuildNumber="17" Version="V2_43" xmlns:h="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" />
  </s:Header>
  <s:Body>
  <m:DeleteItemResponseMessage ResponseClass="Error">
  <m:MessageText>The request timed out.</m:MessageText>
  <m:ResponseCode>ErrorTimeoutExpired</m:ResponseCode>
  <m:DescriptiveLinkKey>0</m:DescriptiveLinkKey>
  </m:DeleteItemResponseMessage>
  </s:Body>
</s:Envelope> 

Note The time of the deletion operation is calculated from when the request is submitted and the response is received.
