使用 iCal 发送电子邮件到带有 valarm 提醒的 outlook

Question

我现在的情况是，我想将带有 iCal 附件的电子邮件发送到 Outlook 日历，并且我想将提醒设置为事件开始前 120 分钟。

我用 iCal 发送 RAW 消息（见下文）。如果收件人打开消息，事件会自动添加到 outlook 日历，但提醒设置为 15 分钟（outlook 中的默认值），即使我在 VALARM 中设置了不同的值。

如果我使用带有 iCal 的 ics 文件导入到 Outlook 日历，则提醒设置为我的值。

非常感谢对此的帮助。如何设置活动提醒？

    $from_name = "<FROM_NAME>";
    $from_address = "<FROM_ADDRESS>";
    $subject = "Meeting Booking";
    $meeting_description = "Here is a brief description of my meeting\n\n";
    $meeting_location = "My Office";
    $domain = 'domain.com';

    $to_name = "<TO_NAME>";
    $to_address = "<TO_ADDRESS>";
    $meeting_date = "2015-10-21 15:40:00";
    $meeting_duration = 3600;

    $meeting_stamp = STRTOTIME($meeting_date . " UTC");
    $dtstart= GMDATE("Ymd\THis\Z",$meeting_stamp);
    $dtend= GMDATE("Ymd\THis\Z",$meeting_stamp+$meeting_duration);

    $mime_boundary = "----Meeting Booking----".MD5(TIME());

Answer 1

我认为你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。仔细想想，这是有道理的：如果你邀请我，我可能想接受或拒绝，但你不应该指手画脚。

另一方面，在导入时，您正在将这些事件变成您自己的。

Answer 2

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.
