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("foo1@foo1.com"))

    message.setRecipient(Message.RecipientType.TO, InternetAddress("foo2@foo2.com"))

    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 @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:SVC_ToGazer@uccint.onmicrosoft.com

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:SVC_ToGazer@uccint.onmicrosoft.com

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.
