我处于这种情况，我想发送带有iCal附件到Outlook日历的电子邮件，我想在开始活动前120分钟设置提醒 .
我用iCal发送RAW消息（见下文） . 如果收件人打开邮件，则会自动将事件添加到Outlook日历中，但即使我在VALARM中设置了不同的值，也会将提醒设置为15分钟（Outlook中的默认值） .
如果我使用iCal的ics文件导入Outlook日历，则提醒设置为我的值 .
我真的很感激这方面的帮助 . 如何设置活动提醒？

我认为您的代码没有任何问题 . 大多数日历客户端将忽略随邀请一起发送的任何警报 . 当你想到这一点时，这是有道理的：如果你邀请我，我可能想接受或拒绝，但是你不应该在我希望收到通知的时候发号施令 .
另一方面，在导入时，您将使这些事件成为您自己的事件 .
将
METHOD:REQUEST更改为METHOD:PUBLISH. 同时将底部的其他方法代码从method=REQUEST更改为method=PUBLISH.
