I'm trying to create a program which help me to import programmatically my school event. The output file (calendarXXXXX...ics) looks like this:

When I try to import this file in Google Calendar it told me that it had elaborated all Y events, but only one was imported. Someone can help me with some suggest?
A event UID is important - it's a unique identifier. If you used xxx for all of them, google probably treated it all as relating the same event.
Try validating your ics files. The validators are not perfect but they help.
https://icalendar.org/validator.html and http://severinghaus.org/projects/icv/ say missing DTSTAMPs
http://ical-validator.herokuapp.com/ says:
! CRLF should be used for newlines
Related RFC 5545 section: 3.1
! UID [xxx] encountered multiple times

I am using ical4j to send out emails with a calendar attachment. I am able to add an organizer based on this SO post: How should I use iCal4j to add a meeting organizer to an iCal event
event.getProperties().add(new Organizer("mailto:bob#example.com"));
The problem is that no attendees added to the calendar is able to cancel an event. If I create (manually, no ical4j) an calendar appointment in Outlook Online, I am able to cancel an event as shown below:
However, the email with an ical4j attachment I received as the organizer (see the above code example) only gives me three options: Yes, No, Maybe as shown below:
How can I make someone among an meeting's attendees be able to cancel the meeting?
------- Update 11/15 -------
Based on the suggestion from #fortuna, my program generated the following event. I am still unable to cancel an event.

I suspect you may need to add something like a participation role to your organizer property:
https://datatracker.ietf.org/doc/html/rfc5545#section-3.2.16
e.g. ORGANIZER;ROLE=CHAIR:bob#example.com
Another way to find out how Outlook does it is to forward the event "as icalendar" to another email address and inspect the ".ics" attachment.
I am trying to generate an ICS file but the problem I am facing is that whenever ICS files is opened in mail via organizer himself the wont will not get added in calender and throw the following error-
Error Displayed is Couldn't Import Calender Try Again Later(You can see it in top left corner of pop-up).
But the same problem is not faced by attendee and they are able to add this meeting successfully
Issue only arise in case of organizer only.
Here organizer is--->
aman.prakash#truminds.com
And attendee is---->
shubham.singh#truminds.com

I tried many things like-->
I added organizer as an attendee
I tried role of that attendee as CHAIR and REQ-PARTICIPANT
Nothing seem to help.
Guys please help me to find solution for this.
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 :

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 need to give my manually built iCal file (.ics) some additional infos which I actually don't want to be visible for Calendar app users. Thus I need to be able to set them manually when creating an Event in an iOS application and (later) reading them from the Calendar events.
I was wondering whether it is possible to add custom fields / attributes to a iCal / .ics file itself (not by using a calendar application!). They shall not be displayed in a Calendar application but accessible for me as a mobile app developer to store IDs, references, anything when I read them out from a calendar on the device... Until now the only possibility seems to be storing those vales as description / notes, but I'm definitely not happy with that!
Is there any possibilltity? Neither could I achieve it by now nor did I find anything useful on the internet...
As an alternative, I was thinking about using the Attachment function of iCal, which - unfortunately - is visible for invited persons and the organizer himself and may not be editable / updated when edited...
Thanks in advance!

You can define your own properties and parameters. Just make sure they start with "X-". For example:

I exported a test all-day event, so I could check the formatting, but it still does not display in the top panel as an all-day event.
Does anyone know how to get an event to appear as an all-day event in Lotus Notes?
The correct solution was to remove the time from the DTSTART and DTEND e.g.
DTSTART;TSID="GMT":20110719T040000 ==> DTSTART;TSID="GMT":20110719
Hope this helps some people.
