Hi I am using cronofy smart invites to create ics calendar file for scheduling meetings in my java applications but when I cancel the meeting the ics file is not supported by outlook its working fine for google and other clients.

the cancel ics file content is :


Event iCalendar in cancel :-
 "BEGIN:
VCALENDAR
VERSION:2.0
PRODID:-//Cronofy//Cronofy0.1//EN
CALSCALE:GREGORIAN
METHOD:CANCEL
BEGIN:VEVENT
DTSTAMP:20200629T133045Z
UID:uid>@invite.cronofy.com
DTSTART:20200709T053000Z
DTEND:20200709T063000Z
DESCRIPTION:Calender test

TRANSP:OPAQUE
ATTENDEE;CUTYPE=INDIVIDUAL;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;X-NUM-GUESTS=0:mailto:<myEmailId>
END:VEVENT
END:VCALENDAR"
 
Event iCalender in create :- 
"BEGIN:
VCALENDAR

PRODID:-//Cronofy//Cronofy 0.1//EN
CALSCALE:GREGORIAN
METHOD:REQUEST
BEGIN:VEVENT

END:VEVENT
END:VCALENDAR"

I have added header as

request.setHeader("Content-Class", "urn:content-  classes:calendarmessage");
request.setHeader("Content-ID", "calendar_message");

The ICS content looks valid, so it could be the format of the email it's attached to.

The iMIP best practices describe the best structure for iCalendar attachments to ensure they can be parsed by most email clients. Using that structure should help Outlook parse the email and attached ICS.

Edit: It's also worth looking at the Cronofy documentation about sending invites for some code examples, or contacting Cronofy support directly.

  • I did try to change the email headers, sending mail by different ways, adding tzid in json which I am sending to cronofy to get tzid added into ics file which did not change the output though and problem still persists I will contact the cronofy support directly thanks. – 00Shunya Jun 30 '20 at 11:27
