I am creating ics file with 2 attendee and a organizer.

Event is properly creating for both attendees and response is also received when they accept/reject the event. I am sending same invite to organizer as well. On organizer end, event is not adding into their calendar (accept/reject buttons are grayed out). Following two messages are showing:

  1. At the meeting organizer, you do not need to respond to the meeting.
  2. Meeting cannot be found in the Calendar.

How I can change the event so that it also create in organizer calendar?

Since it sounds like the ics file is not being generated by the organisers outlook calendar, then two possible solutions suggest themselves:

1) On the assumption that it would be redundant / duplication to add an event to organisers calendar (who would be assumed by the application to have already created the event in itself) possibly the more robust solution for across calendar applications: add a sent-by, as per https://icalendar.org/iCalendar-RFC-5545/3-8-4-3-organizer.html

ORGANIZER;SENT-BY="mailto:[email protected]":
  mailto:[email protected]

2) This might be an outlook bug. A quick search come up with same error messages https://developermessaging.azurewebsites.net/2011/09/30/accepting-ical-appts-in-outlook-when-you-are-the-organiser/ and indicates a hotfix. See also How can I add an ICS meeting automatically to the Organizer's calendar?

Your iCalendar data has an error in organizer, that's why he is not being added to the calendar. As your organizer doesn't have any parameters and only has a cal-address it needs to be separated with colon : not semicolon ;. Correct organizer property:

ORGANIZER:mailto:[email protected]

For more about this property (and iCalendar) you can read here.

RFC 5545 specification of organizer:

organizer = "ORGANIZER" orgparam ":" cal-address CRLF

If this is not only about the organizer showing up in the calendar, then you can find more answers to an actual Outlook error in this SO question.

Finally I found the issue. It was bug in Outlook. I followed the instruction given in following article and it works.
