检查帐户的登录/密码在EWS中是否有效的最佳实践是C#

using System;
using Microsoft.Exchange.WebServices.Data;

namespace EWSAccountValidation
{
    class Program
    {
        static void Main(string[] args)
        {
            // 创建ExchangeService对象
            ExchangeService service = new ExchangeService();

            // 设置Exchange服务器的URL
            service.Url = new Uri("https://example.com/EWS/Exchange.asmx");

            // 设置帐户凭据
            service.Credentials = new NetworkCredential("username", "password");

            try
            {
                // 尝试登录并获取"Inbox"文件夹
                Folder inbox = Folder.Bind(service, WellKnownFolderName.Inbox);
                Console.WriteLine("登录成功，帐户有效。");
            }
            catch (Exception ex)
            {
                Console.WriteLine("登录失败，帐户无效。错误信息：" + ex.Message);
            }
        }
    }
}
