使用Microsoft Graph API代发邮件报错：租户GUID不存在

我们正在开发一款支持定时发送邮件的邮件服务应用，为完成Java环境下Microsoft Graph API的概念验证，已在Azure创建应用、配置权限并添加用户，使用msalj编写了POC代码：

IAuthenticationProvider iAuthProvider = new TokenCredentialAuthProvider(clientSecretCredential());
        
GraphServiceClient<Request> graphClient = GraphServiceClient
                .<Request>builder()
                .authenticationProvider(iAuthProvider)
                .buildClient();

//Creating msg body for Email
Message message = new Message();
graphClient.users(senderUserEmail).sendMail(UserSendMailParameterSet
        .newBuilder()
        .withMessage(message)
        .withSaveToSentItems(saveToSentItems)
        .build()).buildRequest()
    .post();

我们采用ClientCredentialAuth方式获取令牌，已配置ClientID、ClientSecret、TenantId，clientSecretCredential()方法定义如下：

private ClientSecretCredential clientSecretCredential() {
    return new ClientSecretCredentialBuilder()
      .clientId(clientId)
      .tenantId(tenantId)
      .clientSecret(clientSecret)
      .build();
}

调用接口时出现以下错误：

{
  "error": {
    "code": "OrganizationFromTenantGuidNotFound",
    "message": "The tenant for tenant guid {tenantId} does not exist.",
    "innerError": {
      "errorUrl": "https://aka.ms/autherrors#error-InvalidTenant",
      "date": "2024-02-04T11:18:24"
    }
  }
}

更新：已按建议操作但问题仍存在，怀疑缺少Office 365许可证，正在申请测试。
