How to create a .ICS file with multiple VEVENTs to be imported into an existing Outlook Calendar

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:

BEGIN:VCALENDAR
PRODID:-//Company//Product//EN
VERSION:2.0
METHOD:PUBLISH
BEGIN:VEVENT
SUMMARY:Subject of Event
LOCATION:Location of Event
UID:1227559810-8527e2c-20847@domain.com
DESCRIPTION:Some description
DTEND:20081101T200000Z
DTSTART:20081101T200000Z
PRIORITY:3
END:VEVENT
BEGIN:VEVENT
  ...
END:VEVENT
END:VCALENDAR

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.

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.

this is an example of three FIFA 2010 matches on outlook, I'm guessing that this is what you are looking for...
