The following example shows you how to use recursive search to display mailbox folder structure.

C# example

using System;
using System.Net;
using Independentsoft.Webdav.Exchange;
using Independentsoft.Webdav.Exchange.ContentClass;
using Independentsoft.Webdav.Exchange.Properties;
using Independentsoft.Webdav.Exchange.Sql;

namespace Sample
{
    class Program
    {
        static void Main(string[] args)
        {
            NetworkCredential credential = new NetworkCredential("username", "password");
            WebdavSession session = new WebdavSession(credential);
            session.UserMailbox = "https://myserver/exchange/emailaddress";

            Resource resource = new Resource(session);
            Mailbox myMailbox = resource.Mailbox;

            PropertyName[] propertyName = new PropertyName[1];
            propertyName[0] = FolderProperty.IsFolder;

            Select select = new Select(propertyName);
            From from = new From(myMailbox.Root, Scope.Deep);
            Where where = new Where();

            Condition condition1 = new Condition(FolderProperty.IsFolder, Operator.Equals, true);
            where.Add(condition1);

            SqlQuery sqlQuery = new SqlQuery(select, from, where);
            MultiStatus multiStatus = resource.Search(sqlQuery);

            SearchResult searchResult = new SearchResult(multiStatus, propertyName);
            SearchResultRecord[] allRecords = searchResult.Record;

            for (int i = 0; i < allRecords.Length; i++)
            {
                //folder URL
                string folderUrl = allRecords[i].Address;
                Console.WriteLine("folderUrl=" + folderUrl);
            }

            Console.Read();
        }
    }
}
