    我的python代码发送到microsoftoutlook的事件邀请不显示事件标题和描述。 

    if __name__ == "__main__":
    sender = PersonInfo("MY NAME", "ID@gmail.com")
    rec1= PersonInfo("MY NAME", "ID@outlook.com")
    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)

    build_cal_event 如下(为简洁起见,省略了部分代码): 

    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

    它生成以下ICS文件(替换ID和名称以保持机密性):

    这个 SendCalendarInvite 功能如下: 

    def SendCalendarInvite(sender, recipients, subject, body, ics=None):
    aws_region = "us-east-1"
    client = boto3.client('ses',region_name=aws_region)
    
    msg = MIMEMultipart('mixed')
    
    msg["Subject"] = subject
    msg["From"] = sender.email
    msg["To"] = ', '.join(map(lambda x: x.email, recipients))
    msg["Content-class"] = "urn:content-classes:calendarmessage"

    ics_name = "{}.ics".format(subject.replace(" ", "_").upper())


    part_email = MIMEText(body,"html")
    part_cal = MIMEText(ics,'calendar;method=REQUEST')

    msgAlternative = MIMEMultipart('alternative')
    msg.attach(msgAlternative)
    

    ics_name = "{}.ics".format(subject.replace(" ", "_").upper())
    ical_atch = MIMEBase('text', 'calendar', **{'method' : 'REQUEST', 'name' : ics_name})    
    ical_atch.set_payload(ics)
    ical_atch.set_type('text/calendar; charset=UTF-8; method=REQUEST; component = VEVENT')
    encoders.encode_base64(ical_atch)
    ical_atch.add_header('Content-Type', 'text/calendar')
    ical_atch.add_header('charset', 'UTF-8')
    ical_atch.add_header('component', 'VEVENT')
    ical_atch.add_header('method', 'REQUEST')
    ical_atch.add_header('Content-class', 'urn:content-classes:calendarmessage')
    ical_atch.add_header('Content-Disposition', "attachment; filename={}".format(ics_name))
    ical_atch.add_header('Content-ID', 'calendar_message')
    ical_atch.add_header('Content Description', ics_name)
    ical_atch.add_header("Filename", ics_name)
    ical_atch.add_header("Path", ics_name)

    eml_atch = MIMEText('', 'plain')
    encoders.encode_base64(eml_atch)
    eml_atch.add_header('Content-Transfer-Encoding', "")
    msgAlternative.attach(part_email)
    msgAlternative.attach(part_cal)
    
    try:
        result = client.send_raw_email(
            Source=msg['From'],
            Destinations=[recipient.email for recipient in recipients],
            RawMessage={'Data': msg.as_string()}
        )
    except ClientError as e:
        print(e.response['Error']['Message'])
    else:
        print("Email sent! Message ID:"),
        print(result['MessageId'])

    gmail收件人是这样看待邀请的:

    看起来不错。

    Outlook收到的邀请中缺少事件名称和事件说明。如何确保Outlook正确处理由我的代码发送的事件邀请并显示事件名称和说明?

    mime电子邮件如下所示:
