Deleting contacts by using the EWS Managed API 2.0

Example

Deleting a contact

// Bind to an existing contact by using its unique identifier.
Contact contact = Contact.Bind(service, new ItemId("AAMkA="));

// Delete the contact and move the deleted contact to the Deleted Items folder. 
contact.Delete(DeleteMode.MoveToDeletedItems);

The following example shows the XML that is sent by using the Delete method. The ItemId and ChangeKey attributes have been shortened to preserve readability.

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
                   xmlns:m="https://schemas.microsoft.com/exchange/services/2006/messages" 
                   xmlns:t=https://schemas.microsoft.com/exchange/services/2006/types 
                   xmlns:soap="https://schemas.xmlsoap.org/soap/envelope/">
   <soap:Header>
      <t:RequestServerVersion Version="Exchange2010" />
   </soap:Header>
   <soap:Body>
      <m:DeleteItem DeleteType="MoveToDeletedItems">
         <m:ItemIds>
            <t:ItemId Id="AAMkA=" ChangeKey="DwAAA" />
         </m:ItemIds>
      </m:DeleteItem>
   </soap:Body>
</soap:Envelope>

The following example shows the XML that is returned by using the Delete method.

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="https://schemas.xmlsoap.org/soap/envelope/" 
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
               xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Header>
      <t:ServerVersionInfo MajorVersion="14" MinorVersion="0" MajorBuildNumber="639" MinorBuildNumber="11" Version="Exchange2010" 
               xmlns:t="https://schemas.microsoft.com/exchange/services/2006/types" />
   </soap:Header>
   <soap:Body>
      <m:DeleteItemResponse xmlns:t="https://schemas.microsoft.com/exchange/services/2006/types" xmlns:m="https://schemas.microsoft.com/exchange/services/2006/messages">
         <m:ResponseMessages>
            <m:DeleteItemResponseMessage ResponseClass="Success">
               <m:ResponseCode>NoError</m:ResponseCode>
            </m:DeleteItemResponseMessage>
         </m:ResponseMessages>
      </m:DeleteItemResponse>
   </soap:Body>
</soap:Envelope>

Compiling the code

For information about compiling this code, see Getting started with the EWS Managed API 2.0.

Robust programming

• Write appropriate error handling code for common search errors.

• Review the client request XML that is sent to the Exchange server.

• Review the server response XML that is sent from the Exchange server.

• Set the service binding as shown in Setting the Exchange service URL by using the EWS Managed API 2.0. Do not hard code URLs because if mailboxes move, they might be serviced by a different Client Access server. If the client cannot connect to the service, retry setting the binding by using the AutodiscoverUrl(String) method.

• Set the target Exchange Web Services schema version by setting the requestedServerVersion parameter of the ExchangeService constructor. For more information, see Versioning EWS requests by using the EWS Managed API 2.0.

Security

• Use HTTP with SSL for all communication between client and server.

• Always validate the server certificate that is used for establishing the SSL connections. For more information, see Validating X509 certificates by using the EWS Managed API 2.0.

• Do not include user names and passwords in trace files.

• Verify that Autodiscover lookups that use HTTP GET to find an endpoint always prompt for user confirmation; otherwise, they should be blocked.
