创建邮件

命名空间:microsoft.graph

采用 JSON 或 MIME 格式创建新邮件的草稿。

使用 JSON 格式时,可以:

  • 包含附件邮件中。
  • 随后更新草稿以将内容添加到正文,或更改其他邮件属性。

使用 MIME 格式时:

  • 提供适用的 Internet 邮件头MIME 内容,所有内容在请求正文中都通过 base64 格式进行编码。
  • * 向 MIME 内容添加任何附件和 S/MIME 属性。

默认情况下,此操作将草稿保存在“草稿”文件夹中。

在后续操作中发送草稿消息。

或者,通过一次操作发送新邮件 ,或创建一个草稿以转发答复答复所有现有邮件。

* 注意: S/MIME 消息有效负载当前限制为 4 MB。 超过此限制的提交尝试将导致 HTTP 413 Request Entity Too Large错误响应。
