Send ics file RSVP format not working properly using Outlook smtp server?

I have a code that works well when using gmail smtp server with my personal credentials :

fun sendEventInvitation(from: Profile, to: Profile, meetup: Meetup) {
    val message: MimeMessage = emailSender.createMimeMessage()

    message.setFrom(InternetAddress("[email protected]"))
    message.setRecipient(Message.RecipientType.TO, InternetAddress("[email protected]"))
    message.subject = "foo"

    val messageBodyEvent = MimeBodyPart()
    val id = UUID.randomUUID().toString()
    val eventIcs = formatCalendarFile(id, from, to, meetup)
    messageBodyEvent.dataHandler = DataHandler(ByteArrayDataSource(eventIcs, "text/calendar; charset=\"utf-8\"; method=REQUEST"))
    messageBodyEvent.setHeader("Content-Transfer-Encoding", "base64")

    val multiPart = MimeMultipart()
    multiPart.addBodyPart(messageBodyEvent)

    message.setContent(multiPart)

    emailSender.send(message)
}

eventIcs is basically a String of an iCal correct format.

But whenever I switch to the outlook server using company's credentials, It gives the following error :

554 5.2.0 STOREDRV.Submission.Exception:InvalidRecipientsException; Failed to process message due to a permanent exception with message A message can't be sent because it contains no recipients. InvalidRecipientsException: A message can't be sent because it contains no recipients. [Hostname=AM6PR01MB5011.eurprd01.prod.exchangelabs.com]
DEBUG SMTP: got response code 554, with response: 554 5.2.0 STOREDRV.Submission.Exception:InvalidRecipientsException; Failed to process message due to a permanent exception with message A message can't be sent because it contains no recipients. InvalidRecipientsException: A message can't be sent because it contains no recipients. [Hostname=AM6PR01MB5011.eurprd01.prod.exchangelabs.com]

Now, weirdly enough, when I remove the method=REQUEST attachment header :

messageBodyEvent.dataHandler = DataHandler(ByteArrayDataSource(eventIcs, "text/calendar; charset=\"utf-8\"))

It works but because there's not this header, the ICS isn't well recognized by Outlook client and doesn't display RSVP options to the recipients as explained here.

I tried to send an invitation from Thunderbird using the same credentials and it works. So it's not link to rules whatsoever.

Here is the complete debug output :

Any ideas why there is this behavior ?

As mentioned before, there are several types of online validators that can check if the format is valid. These two validators detect different types of errors.

For example, one of the things the validators will notice is that, whenever you use text, you have to escape the following characters: \ ; , \n

Some things the validators treat as warnings (no CRLF line breaks, too much characters in the same line) can be ignored.

There are some errors that the validators won't be able to detect. For example, I got this SMTP error when the organizer's email was equal to the recipient's email. Finding it was non-obvious but I finally detected the source of the problem.

ORGANIZER;CN=Example:mailto:[email protected]

I hope Outlook can improve the feedback / error messages for iCal validation!

As mentioned @Bill Shannon in the comment section, the problem came from the calendar formatting.

You need to make sure your ics pass this kind of validator.

For example, in my implementation :

"""BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//GRTgaz Corporation//NONSGML Togaz'er//FR
METHOD:REQUEST
BEGIN:VEVENT
UID:$id
ORGANIZER;RSVP=FALSE;PARTSTAT=ACCEPTED;
ROLE=CHAIR:mailto:[email protected]
ATTENDEE;RSVP=FALSE;PARTSTAT=ACCEPTED;
ROLE=REQ-PARTICIPANT:mailto:${to.email}
DTSTAMP:${startDate[0]}T${startDate[1]}Z
DTSTART:${startDate[0]}T${startDate[1]}
DTEND:${endDate[0]}T${endDate[1]}
SUMMARY:${meetup.name}
LOCATION:${meetup.address}
DESCRIPTION:${meetup.description}
END:VEVENT
END:VCALENDAR
"""

The ORGANIZER and ATTENDEE props weren't valid. the property ROLE must be in the same line. So I modified it to:

"""BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//GRTgaz Corporation//NONSGML Togaz'er//FR
METHOD:REQUEST
BEGIN:VEVENT
UID:$id
ORGANIZER;RSVP=FALSE;PARTSTAT=ACCEPTED;ROLE=CHAIR
 :mailto:[email protected]
ATTENDEE;RSVP=FALSE;PARTSTAT=ACCEPTED;ROLE=REQ-PARTICIPANT
 :mailto:${to.email}
DTSTAMP:${startDate[0]}T${startDate[1]}Z
DTSTART:${startDate[0]}T${startDate[1]}
DTEND:${endDate[0]}T${endDate[1]}
SUMMARY:${meetup.name}
LOCATION:${meetup.address}
DESCRIPTION:${meetup.description}
END:VEVENT
END:VCALENDAR
"""

Now, it works properly.
