【问题描述】：

我正在尝试通过 python exchangelib 包将 HTML 表格发送到 Outlook 电子邮件中。但是，当在交付端收到电子邮件时，它会将 HTML 内容显示为纯文本。这一定是什么原因？我们如何在 exchangelib 中设置 MIME 版本和内容类型。

如果有人能确定为什么它没有按照我们在电子邮件中的要求呈现，我们将不胜感激。请给我一个关于如何在 exchangelib 中实现 mime 和 content-type 的建议

【解决方案1】：

要将您的电子邮件正文标记为 HTML，您需要创建一个 HTMLBody 实例：email_body = HTMLBody(self.create_html_body())。见https://ecederstrand.github.io/exchangelib/#creating-updating-deleting-sending-moving-archiving-marking-as-junk
