The event invitation sent by my python code to Microsoft Outlook does not show the event heading and description.
if __name__ == "__main__":
sender = PersonInfo("MY NAME", "[email protected]")
rec1= PersonInfo("MY NAME", "[email protected]")
rec2= PersonInfo("NAME", "ID2gmail.com")
recipients = [rec1, rec2]
subject = "Hi"
body = "How is everything?"
dtstart = datetime(2020, 9, 3, 22, 15, 0)
dtend = datetime(2020, 9, 3, 22, 30, 0)
ics = build_cal_event("ImpEvent", "Greeting", sender, recipients, dtstart, dtend) #Creates ICS file
with open("event.ics", 'w') as f:
f.write(ics)
SendCalendarInvite(sender, recipients, subject, body, ics)
The function build_cal_event
is as follows (omitted some of the code for brevity):
def build_cal_event(event_name, event_description,
organizer, attendees,
dtstart, dtend):
# cal = icalendar.Calendar()
str_list = []
str_list.append('''
BEGIN:VCALENDAR
METHOD:REQUEST
..........
END:VEVENT
END:VCALENDAR
'''.format(datetime.now().strftime("%Y%m%dT%H%M%SZ")))
cal = ''.join(str_list)
return cal
It generates the following ICS file (replaced IDs and names to preserve confidentiality):

The gmail recipient sees the invitation in this way:
It looks okay.
However, the event invitation for the Outlook recipient looks like this:
The event name and event description are missing in the invitation received by Outlook. How can I ensure that Outlook correctly processes the event invitation sent by my code and shows the event name and description?
EDIT 1:
The mime email looks like this:
Content-Type: multipart/mixed; boundary="===============1597738219983052864=="

EDIT 2:
My concern is why is the event name not being detected when the mime email contains it: DESCRIPTION;LANGUAGE=en-US:impevent
