Question

我们需要告知客户即将到来的约会。因此，我向他们发送iCalendar邀请，以便在他们的日历中创建约会。 iCalendar邀请的示例如下所示。

所以问题是GMail不显示X-ALT-DESC参数的html内容。好奇，Hotmail的一切正常 - 它显示事件面板，其中包含“Accept”，“Ignore”按钮和来自X-ALT-DESC的格式化html消息。 GMail仅显示活动信息面板。

Answer 1

X-ALT-DESC是特定于MSFT的扩展程序（请参阅MSND on iCalendar/X-ALT-DESC）你可以查看RFC进行仔细检查。

鉴于与Microsoft的Hotmail关系，它们支持它是有道理的，并且可能还有一些意义，即为什么Google不支持MSFT专有功能。
