我使用以下程序运行了您的 ICS 文件：
from icalendar import Calendar, Event
from datetime import datetime
cal = open('test.ics','rb')
ical = Calendar.from_ical(cal.read())
for component in ical.walk():
if component.name == 'VEVENT':
for item in component.sorted_items():
if item[0] == 'RECURRENCE-ID':
reoccur_item = item[1]
print reoccur_item.params
print reoccur_item.dt
continue
if item[0] == 'DTSTART':
print 'DSTART', item[1].dt
continue
if item[0] == 'DTEND':
print 'DTEND', item[1].dt
continue
if item[0] == 'DTSTAMP':
print 'DTSTAMP', item[1].dt
continue
print item
cal.close()
以下是我获得的输出

重复发生规则为空，这几乎看起来像重复发生事件的单个实例，但最终是各种 Microsoft 特定数据。其序列号为 8，X-MS-OLK-APPTLASTSEQUENCE:16 表明最后一个实例应具有序列 16。
它几乎看起来像是在每个具有相同 UID 的团队上创建了带有序列标记的多个实例
