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 Microsoft Exchange Web Services (EWS) Managed API to obtain the configuration settings for a user. The Autodiscover service returns only the configuration settings requested. If a requested setting is not implemented on the Exchange server, no element is returned.

To get the user settings

  1. Use the GetUserSettings method to generate the request that retrieves configuration information for a user, as shown in the following example. In this example, only some of the possible user settings are requested, and only the requested settings are returned from the server.

    AutodiscoverService autodiscoverService = new AutodiscoverService("domain.contoso.com");
    autodiscoverService.Credentials = new NetworkCredential("User1", "password", "domain.contoso.com");
    
    // Submit a request and get the settings. The response contains only the
    // setttings that are requested, if they exist.
    
    GetUserSettingsResponse userresponse = autodiscoverService.GetUserSettings(
        "User1@Contoso.com",
        UserSettingName.UserDN,
        UserSettingName.UserDeploymentId,
        UserSettingName.InternalMailboxServer,
        UserSettingName.MailboxDN,
        UserSettingName.PublicFolderServer,
        UserSettingName.ActiveDirectoryServer,
        UserSettingName.ExternalMailboxServer,
        UserSettingName.EcpDeliveryReportUrlFragment,
        UserSettingName.EcpPublishingUrlFragment,
        UserSettingName.EcpTextMessagingUrlFragment, 
        UserSettingName.ExternalEwsUrl,
        UserSettingName.CasVersion,
        UserSettingName.EwsSupportedSchemas);
    
  2. Parse the collection to display each element of the returned key value pair. The following example shows how to parse through each returned element and display the name and value of each key value pair.

    // Display each retrieved value. The settings are part of a key value pair.
    foreach (KeyValuePair<UserSettingName, Object> usersetting in userresponse.Settings)
    {
        Console.WriteLine(usersetting.Key.ToString() + ": " + usersetting.Value);
    }
    

    Alternatively, you can obtain the value of a specific element. In the following example, the UserDisplayName setting is to be displayed.

    // Display a specific setting, such as UserDisplayName.
    Console.WriteLine(userresponse.Settings[UserSettingName.UserDisplayName]);
    

Example

The following example shows how to create an AutodiscoverService object and uses the GetUserSetting method to obtain and display a user's configuration settings.

AutodiscoverService autodiscoverService = new AutodiscoverService("domain.contoso.com");
autodiscoverService.Credentials = new WebCredentials("User1", "password", "domain.contoso.com");


// Get the user settings.
// Submit a request and get the settings. The response contains only the
// settings that are requested, if they exist. 
GetUserSettingsResponse userresponse = autodiscoverService.GetUserSettings(
    "User1@Contoso.com",
    UserSettingName.UserDN,
    UserSettingName.UserDeploymentId,
    UserSettingName.InternalMailboxServer,
    UserSettingName.MailboxDN,
    UserSettingName.PublicFolderServer,
    UserSettingName.ActiveDirectoryServer,
    UserSettingName.ExternalMailboxServer,
    UserSettingName.EcpDeliveryReportUrlFragment,
    UserSettingName.EcpPublishingUrlFragment,
    UserSettingName.EcpTextMessagingUrlFragment, 
    UserSettingName.ExternalEwsUrl,
    UserSettingName.CasVersion,
    UserSettingName.EwsSupportedSchemas);

// Display each retrieved value. The settings are part of a key value pair.
foreach (KeyValuePair<UserSettingName, Object> usersetting in userresponse.Settings)
{
    Console.WriteLine(usersetting.Key.ToString() + ": " + usersetting.Value);
}

The following example shows the XML request that is sent by the client to the server when the client submits an Autodiscover request.

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.
