Outlook 2013 邀请未显示嵌入附件 - 文本/日历；方法 = 请求

【中文标题】Outlook 2013 邀请未显示嵌入附件 - 文本/日历；方法 = 请求【英文标题】：Outlook 2013 invite not showing embeded attachment - text/calendar;method=REQUEST 【发布时间】：2015-06-16 18:53:17 【问题描述】：

我正在创建一个文本/日历类型的电子邮件。它有 3 个备用视图：文本、html，最后一个是会议邀请或 .ics。我没有附加 ics，而是将其放在第三个视图的内容中。

当我发送它时，outlook 2013 会正确接收邀请并在消息顶部显示接受/暂定/拒绝按钮。

但是，当我尝试将附件嵌入到活动/会议中时，它根本无法抓取它。

如果我将 ics 作为附件发送，它将嵌入附件，但是用户必须单击 .ics 文件，而不是获得内联的 Accept/Tentative/Decline。

我用一种叫做 tcl 的脚本语言来生成这个。我正在使用 mime 和 smtp 库。我一直在参考 tcl、c#、php 和 java 实现，但似乎没有人记录过这个确切的场景。

如果需要，我可以发布我的代码，但它完全无关紧要。相关的是正在构建的 mime 消息。

如何将附件嵌入到事件/日历项目中？

这是由 mime 库生成的，正如我所说，如果我作为附件发送它就可以工作。它只是在使用 text/calendar;method=REQUEST 并将其放置在替代视图中时不起作用

我怀疑它与我的 mime 消息（电子邮件）结构或其标题有关

更新 1：

这是我的新代码，建议采用更扁平的结构。无论内容类型是否具有字符集以及是否具有内容传输，似乎都没有区别。仍会收到电子邮件，并显示接受/暂定/拒绝按钮，但没有附件：

【问题讨论】：

你必须创建一个multipart/mixed，它包含两个部分：multipart/alternative 和附件。 multipart/alternative 应该包含 text/html 和 text/plain 可能还有 ics 部分。不确定最后一件事。我认为您指的是仅发送 .ics 附件，或者可能发送带有接受/暂定/拒绝按钮的邀请请求。我在那里没有问题，我的电子邮件有效。不工作的是事件内的嵌入附件。请参阅 ATTACH 段。我以为你想发送一封带有附件和 .ics 的电子邮件。 【参考方案1】：

Outlook 期望会议请求 MIME 消息是单个部分 - 文本/日历。纯文本和 HTML 必须在 VEVENT 部分（分别为 DESCRIPTION 和 X-ALT-DESC）。附件也必须作为 ATTACH 部分添加：

【讨论】：

我希望它是一个请求，而不是一个发布。这似乎也无效，因为它没有开始和结束时间，我不确定你是否把它留了简短......我已经用我认为你的建议更新了我的问题，但它仍然没有工作。这只是一个显示DESCRIPTION、X-ALT-DESC和ATTACH部分的例子。好吧，我就是这么想的。我仍然无法让它工作 - 我的最新版本在更新的问题中。看来我错了，Outlook 本身发送了一个包含多部分/混合附件的邀请。你读过那个，或者你有 mime 输出吗？我尝试发送混合但无法正常工作，我会再试一次......

以上是关于Outlook 2013 邀请未显示嵌入附件 - 文本/日历；方法 = 请求的主要内容，如果未能解决你的问题，请参考以下文章

仅保存 Outlook MailItem 的真实附件

通过 python 发送时附件不显示在 Outlook 中

Outlook 将图像显示为在邮件的 HTML 正文中引用的附件

逻辑应用和 Outlook 嵌入图像

是否可以像 Outlook RTF/TNEF 那样在 html 电子邮件中嵌入非图像附件？

无法在使用 python smtplib/email 发送的 Outlook 2013 电子邮件中显示嵌入图像
