无法使用Office 365 REST API发送大邮件

我正在使用JavaScript发出POST请求以使用xhr创建到Office 365的消息(或者使用法拉第gem发出POST请求-Ruby on Rails).我的流程是将文件编码为base64并创建一个包含所有内容的JSON附件(已编码)，然后发布到https://outlook.office.com/api/v1.0/me/sendmail.

I'm using JavaScript to make a POST request to create a message to Office 365 with xhr (Or using Faraday gem to make POST request - Ruby on Rails).My flow is encode file to base64 and create a JSON contain all attachments(encoded) then POST to https://outlook.office.com/api/v1.0/me/sendmail.

var endpointUrl = "https://outlook.office.com/api/v1.0/me/sendmail";
    var xhr = new XMLHttpRequest();
    xhr.open("POST", endpointUrl);
    xhr.setRequestHeader("Authorization", "Bearer " + token);
    xhr.setRequestHeader("content-type", "application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=false;charset=utf-8");
    xhr.send(JSON.stringify(result));
}

此代码可以发送带有大约22.5MB附件的消息，但是如果所有附件的大小都超过23MB，我将收到404错误响应，并且控制台将写入:

This code can send message with about 22,5MB attachments, but if all attachments have more than 23MB, I got 404 error reponse and the cosole write:

XMLHttpRequest无法加载 https://outlook.office.com/api/v1.0/me/sendmail .不 请求中存在"Access-Control-Allow-Origin"标头 资源.因此，不允许使用来源' http://localhost:3000 使用权.响应的HTTP状态代码为404.

XMLHttpRequest cannot load https://outlook.office.com/api/v1.0/me/sendmail. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. The response had HTTP status code 404.

将message size restrictions设置为最大153600 有人可以帮我吗?谢谢！
