有没有办法用C#的API在office365中创建共享邮箱？

using Microsoft.Graph;
using Microsoft.Identity.Client;
using System;

class Program
{
    static async System.Threading.Tasks.Task Main(string[] args)
    {
        // 配置应用程序凭据
        var clientId = "YourClientId";
        var clientSecret = "YourClientSecret";
        var tenantId = "YourTenantId";

        // 创建身份验证提供程序
        var clientApplication = ConfidentialClientApplicationBuilder
            .Create(clientId)
            .WithClientSecret(clientSecret)
            .WithAuthority($"https://login.microsoftonline.com/{tenantId}")
            .Build();

        // 获取访问令牌
        var authResult = await clientApplication.AcquireTokenForClient(new[] { "https://graph.microsoft.com/.default" }).ExecuteAsync();
        var accessToken = authResult.AccessToken;

        // 创建共享邮箱
        var graphClient = new GraphServiceClient(new DelegateAuthenticationProvider((requestMessage) =>
        {
            requestMessage.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", accessToken);
            return System.Threading.Tasks.Task.CompletedTask;
        }));

        var mailbox = new MailboxSettings
        {
            EmailAddress = new EmailAddress
            {
                Address = "sharedmailbox@example.com",
                Name = "Shared Mailbox"
            },
            AutoReplySettings = new AutoReplySettings
            {
                Enabled = true,
                ExternalAudience = ExternalAudienceScope.All,
                InternalReplyMessage = "Internal auto-reply message",
                ExternalReplyMessage = "External auto-reply message"
            }
        };

        await graphClient.Users["user@example.com"].MailboxSettings.SharedMailboxes
            .Request()
            .AddAsync(mailbox);

        Console.WriteLine("Shared mailbox created successfully.");
    }
}
