带有空间/ ICalendar的ICalendar-生成器创建新会议，而不是在Outlook中更新

Question

在查看了下面的question on SO之后，我添加了一些附加字段，并删除了ICS文件中的一些当前字段。

我的邀请如下：

BEGIN:VCALENDAR
VERSION:2.0
PRODID:spatie/icalendar-generator

现在我想更新时间，所以我重新发送一个更新ICS，如下所示：

BEGIN:VCALENDAR

PRODID:spatie/icalendar-generator

我在发送更新时添加了X-MS-OLK-FORCEINSPECTOROPEN、X-WR-RELCALID并删除了X-WR-CALNAME，正如前面的SO线程所解释的那样，但这仍然会在Outlook中生成一个新事件，用于更新当前事件。

有人能为我指出正确的方向吗？

Answer 1

从链接原始的SO问题中可以看到，METHOD字段需要一个值(您目前缺少该字段)，以便能够在Outlook中更新邀请

总之，除了

和SEQUENCE:

之外，您还必须指定UID:和ORGANIZER:xxxxxxxx
