I am trying to generate iCalender files in asp.net. An ics file with below details is downloaded for the user and when user clicks it it opens the outlook calender entry which the user have to Save and close again.
Can we make it a one stop process where user just have to click the file and it goes to outlook calendar directly?
Please note the 'Automatically accept meetings' setting in outlook is turned on. What am i missing then.
Thanks for the help.

What I think is you can't accept meeting of some one else through ICS. But you can give a try for STATUS: CONFIRMED

I have a ICS feed for a calendar, that I subscribe from Google calendar.
As soon as I add the feed, it shows all the events perfectly. But when I edit events, it doesn't update. So it seems like it can read the feed, but doesn't sync it.
If I remove the feed and add it again, its still not synced. But if I add a parameter to the url (ex. &x=1), it will import the updates, but still not sync. So it seems like Google is caching the feed pr. url, but doesn't sync after the url has been added.
Anyone else had this issue, or know a solution?
SOLUTION UPDATE: 12/03 - 2020
I missed the fields "SEQUENCE" and "LAST-MODIFIED". Credits to #anmari for spotting the error.
The calendar now syncs perfectly with Google.

to tell any calendar application that an event has been updated (so that it will sync it) one needs fields to be updated for the event that is being modified, and add:
LAST-MODIFIED:19960817T133000Z
SEQUENCE:1 (of update)

Is there a way to backup a Google calendar and then import it while saving the creation dates of events? This is critical for me to calculate when appointments were created (weekly billing cycle), as opposed to when they are scheduled for (perhaps months down the road).
I've tested it, and when you import and exported calendar, it marks all events as created on the date they were imported on, not when they were actually created, which is ludicrous.
Does anyone know a work around to save the getCreated date?
Thanks a bunch, Bob
You can open the .ICS file of the exported calendar and check the event creation date and time. Every event starts with a BEGIN and ends with an END tag as below:

I'm trying to add recurring events to my personal calendar via .ics, The client imports and adds the first event to the calendar but doesn't create other repeating events.
I'm actually creating a recurring event which happens daily, below is the sample of my .ics file.

looks like the problem is with the client s/w, not your ics file.
Your code above validates at http://severinghaus.org/projects/icv/
and loads and recurs fine in google calendar.
see https://www.google.com/calendar/embed?src=jpkdu09olie8uveopl72oguj2s%40group.calendar.google.com&ctz=Australia/Sydney
Cross test on some more other calendar clients to verify.
We are working on an asp.net 2.0 web app that emails users an ical to save to their outlook 2003 calendar. We noticed none of the code to update or delete an item seem to work even though the ical 2.0 spec supports it. We are curious if Outlook 2003 just ignores this? Does Outlook 2007 act differently?
We have situations where an event may change or be cancelled which fires off an email notification but the updated ical just adds a new event, it nevers deletes and or moves the original....
Are we missing something?
We have been able to get it to delete a message now.... but not update the way we thought it would....
to setup a meeting we send...

Our original issue with the deleting is we had a blank organizer line. We removed that and canceling worked....
As for updating an original publish like in the first line, we have been unable to. We have increased the sequence # from zero to 1 and it just adds a new meeting. We are using the same UID number which in our testing is just 12345.
The only way I have found to do this is to create an organizer and change from publish to a request type.
In reading the rfc2445 this seems to be how it's designed. Publish will always create a new record and sequence doesn't matter. When sequence matters is with an organizer and request method....
I also found this answer after my testing and reading on stackoverflow here:

I'd have to say my experiences with Outlook 2007 are the same as yours with Outlook 2003 .. it totally ignores PUBLISH..
The best way i've come around this is to use the meeting as an attachment.. that way you can open it, 'make it your own' and make use of Tracking and send out updates to attendee's ..
I don't think Microsoft is interested in playing nice with standards here..
I have a need to allow for a user to download an event that has multiple meeting dates. To do this I have created a memorystream to be downloaded which produces a .ics file. For example:

If I only include one VEVENT in this file it will save it to my existing Outlook calendar. However, when I have multiple VEVENTs it wants to open it as a new calendar and files it under "Other Calendars".
Is there a way (without using File - Import from within Outlook) to specify that the calendar should be imported automatically into the existing calendar when opened?
UPDATE: To clarify, each VEVENT is related to a single "Appointment". However there may or may not be a recurring pattern.
-Mike
I don't think this will work. Outlook is limited in importing those "open" specs. I had a similar problem trying to import a vCard file with multiple contacts. I ended up splitting the file and writing a script in Outlook to import all the files in a directory.
This is possible, using an Internet Calendar (like from Google). Outlook 2007 has the capabilities to subscribe to an Internet Calendar (under Account Settings) and Outlook 2003 has an open-source plug-in available. You could create an accessible feed that is "read-only". The format is like

Make sure you are using a unique UID for every VEVENT. If you use the same UID for every VEVENT you would see exactly the behavior you are describing since only unique UID's are processed and added to the calendar.
HTH.
This should be possible :/ the following works with google, and loads fine into entourage. Outlook seems to have some issues though, will keep looking.
NOTE - this does import correctly into outlook when you use file>import etc, it's only double clicking that causes it to only load the first event.

Make sure you have "X-MS-OLK-FORCEINSPECTOROPEN:TRUE" in the VCALENDAR part of your file. This allows an ICS file with multiple VEVENTs to import into your default calendar in Outlook. No new calendar created.
This works: Take the ICS file, drag & drop on the calendar button in Outlook (bottom left corner on mine). That adds multiple entries to the default calendar, without any prompting when an ICS file contains multiple vevents. Updates & deletes of multiples are my next challenge.
Double clicking the same file has very different results: Creates a new calendar, and the busy indicator is ignored. The drag & drop that I described keeps the busy indicator intact like it is in the ICS file
X-MS-OLK-FORCEINSPECTOROPEN:TRUE opened the 1st entry so it could be approved & added. Subsequent vevents are ignored.
X-MS-OLK-FORCEINSPECTOROPEN:FALSE or removing the line entirely had the same results on Outlook 365 for me.
Also, when double clicking an ICS file with multiple vevents, this is what I saw: Outlook is not entirely compatible because a new calendar gets created named "untitled". The mail app that comes with Windows 10 is compatible & all entries are added to the calendar properly (might be because the Win 10 mail app only has 1 calendar? I don't know- I'm writing for Outlook only)
