Finding Folders (Exchange Web Services)

Topic Last Modified: 2007-09-14

You can use Exchange Web Services to find subfolders of an identified folder.


The following example shows you how to search for all subfolders in the root folder.

ExchangeServiceBinding esb = new ExchangeServiceBinding ();
esb.Credentials = new NetworkCredential("UserName", "Password", "Domain");
esb.Url = @"";

// Create the request and specify the travesal type.
FindFolderType findFolderRequest = new FindFolderType();
findFolderRequest.Traversal = FolderQueryTraversalType.Deep;

// Define the properties that are returned in the response.
FolderResponseShapeType responseShape = new FolderResponseShapeType();
responseShape.BaseShape = DefaultShapeNamesType.Default;
findFolderRequest.FolderShape = responseShape;

// Identify which folders to search.
DistinguishedFolderIdType[] folderIDArray = new DistinguishedFolderIdType[1];
folderIDArray[0] = new DistinguishedFolderIdType();
folderIDArray[0].Id = DistinguishedFolderIdNameType.inbox;

// Add the folders to search to the request.
findFolderRequest.ParentFolderIds = folderIDArray;

    // Send the request and get the response.
    FindFolderResponseType findFolderResponse = esb.FindFolder(findFolderRequest);

    // Get the response messages.
    ResponseMessageType[] rmta = findFolderResponse.ResponseMessages.Items;

    foreach (ResponseMessageType rmt in rmta)
        // Cast to the correct response message type.
        if (((FindFolderResponseMessageType)rmt).ResponseClass == ResponseClassType.Success)
            Console.WriteLine("Folder found");
catch (Exception e)

You can also create a folder by using an XML message. For more information, see FindFolder Operation. The FindFolder operation is also used to find managed custom folders.

The SOAP messages that are passed between the Exchange Web Services client and server are defined by the XML schema and WSDL files. The XML schema and WSDL files define the contract between the client and server. Proxy class generators create an object-model abstraction of those SOAP messages, which can simplify programming. This code example uses a proxy class library that was generated by Microsoft Visual Studio 2005. Different proxy class generators create different object models for a given Web service. This proxy class code example is an illustration only. Refer to the proxy class generator documentation for support for proxy classes.

Compiling the Code

For information about compiling the code, see Exchange Web Services Client Development.

Robust Programming

The namespace for the proxy assembly is defined when the proxy assembly is created.
