Creating user configuration objects by using the EWS Managed API 2.0

Last modified: February 06, 2014

Applies to: EWS Managed API | Exchange Server 2010

Note: This content applies to the EWS Managed API 2.0 and earlier versions. For the latest information about the EWS Managed API, see Web services in Exchange.

You can use the Exchange Web Services (EWS) Managed API to create user configuration objects on folders in a mailbox.

Note

The user configuration objects feature is available in versions of Exchange starting with Exchange Server 2010.

Example

The following example shows how to create a user configuration object with XML and binary data on the Inbox folder.

static void CreateUserConfiguration(ExchangeService service, 
                                    byte [] xmlData, 
                                    byte [] binaryData)
{
   // Create the user configuration object.
   UserConfiguration config = new UserConfiguration(service);

   // Add user configuration data to the XmlData and BinaryData properties.
   config.XmlData = xmlData;
   config.BinaryData = binaryData;

   // Name and save the user configuration object on the Inbox folder.
   // This results in a call to EWS.
   config.Save("MyCustomSettingName", WellKnownFolderName.Inbox);
}

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.
