带有文本和日历的多部分电子邮件：Outlook无法识别ics [英] Multipart email with text and calendar: Outlook doesn't recognize ics

问题描述

我在Outlook 2007中遇到问题。当发送带有文本/日历部分的多部分/备用电子邮件时，Outlook会识别日历事件，这是它的原因。
但是当添加text / plain部分时，Outlook只显示纯文本，日历部分缺失（但它出现在电子邮件的源代码中）。

I have problems with Outlook 2007. When sending a "multipart/alternative" email with a "text/calendar" part, Outlook recognizes the calendar event, that's how it has to be. But when adding a "text/plain" part, Outlook only displays the plain text, the calendar part is missing (but it's present in the source code of the email).

源代码如下：

[...]
Content-Type: multipart/alternative;
boundary="_=_swift_v4_138243630552664dd1bc83e_=_"

--_=_swift_v4_138243630552664dd1bc83e_=_
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable

[...the plain message...]

--_=_swift_v4_138243630552664dd1bc83e_=_
Content-Type: text/calendar; charset=utf-8
Content-Transfer-Encoding: quoted-printable

推荐答案

您缺少iTIP方法，内容类型：

You are missing the iTIP method, both in the content-type:

Content-Type: text/calendar; charset="utf-8"; method=REQUEST

并作为VCALENDAR属性：

and as a VCALENDAR property as well:

BEGIN:VCALENDAR
VERSION:2.0
METHOD:REQUEST
PRODID:-//GourmetPortal//NONSGML rr//DE

方法可能是PUBLISH或REQUEST（在这种情况下，您也会错过一些ATTENDEE属性）。

The method might be PUBLISH or REQUEST (in which case you also miss some ATTENDEE property).

然后，一些客户端忽略了multipart / alternative中的iMIP，并且只查看附件，因此您可能需要尝试以下结构：

Then, some clients are ignoring iMIP in multipart/alternative and are looking only as attachments so you may need to try the following structure:

multipart/mixed
  multipart/alternative
    text/plain
    text/calendar;method=REQUEST
  text/calendar (with a content-disposition:attachment)

本质上，您要添加附件两次。 iMIP邀请来自google / yahoo日历和闪电都有这样的结构。

Essentially, you are adding the attachment twice. iMIP invitation from google/yahoo calendar and lightning have such a structure.
