Steps to Reproduce

Refer instructions mentioned on the PDN -

Root Cause

The 'SendEmailMessage' function implementation in Pega-IntegrationEngine:06-02-25, has capabilities to send email and it does not handle iCalendar meeting requests. Additionally, user has requirements that attendees who receives the meeting invite, they should get the options (Edit the Response before Sending, Send the Response Now, Do Not Send a Response) similar to the options when similar meeting invite is sent directly from MS Outlook.


Following local change has been suggested to user which helps meet the requirements.

1) Create a Text mode Property by name "pyAttendee", applies to Data-Email-MeetingRequest" class
2) In FUNCTION Default • SendEmailMessage, uncomment the "Handle iCalendar meeting requests" part of code

                 /* Handle iCalendar meeting requests
                ClipboardProperty meetingDataRef = MessageData.getProperty("pyMeetingData");
                if (!meetingDataRef.isEmpty())
                                // Add a header for the 

                                message.addHeader("component", "VEVENT");

                                // Format the meeting data into a string
                                String meetingData = FormatMeetingRequest(meetingDataRef.getPageValue());
                                MimeBodyPart meetingPart = new MimeBodyPart();
                                meetingPart.setDataHandler(new DataHandler(
                                new javax.mail.util.ByteArrayDataSource(meetingData, "text/calendar")));


3) In FUNCTION Default • FormatMeetingRequest , add following code snippet in "Extract meeting request values" part of code
              String attendee = MeetingRequestData.getString("pyAttendee");

4) In FUNCTION Default • FormatMeetingRequest , add the below statement after BEGIN:VEVENT and before DTSTART part of code which appends string values to a buffer. 
              + "ATTENDEE;ROLE=REQ-PARTICIPANT;RSVP=TRUE:MAILTO:" + attendee + "\n"
Note: this piece of code need to be repeated for sending the meeting invite to multiple attendees.

5) Set pyAttendee property value while invoking the SendEmailMessage RUF for sending a meeting request.
