ICS File (used with Outlook)

[Guest]

Hello..
I'm trying to build an ics file that I can attach to an E-Mail programmatically
I have succeeded in building one for a meeting and it works fine
Building the file is no problem the structure is spelled out on
http://www.imc.org
The problem is when I try to build one for a task, Outlook can't import it
I get the message "Cannot import vCalendar file"
I suspect that something must be wrong with the file structure.
I'm hoping someone might have some examples of an ICS file for a task (todo) that works
The other possibility is that the file type for a task is something other than ics

a sample of the file I created follows

BEGIN:VCALENDA
PRODID:-//Microsoft Corporation//Outlook 9.0 MIMEDIR//E
VERSION:2.
BEGIN:VTOD
UID:[email protected]
ORGANIZER:MAILTO:[email protected]
ATTENDEE;CN="joe";ROLE=OPT-PARTICIPANT;RSVP=FALSE:MAILTO:[email protected]
DTSTAMP:20040414T161733
DTSTART:20040419T210000
DUE:20040422T230000
SUMMARY:A Tas
PRIORITY:
STATUS:NEEDS-ACTIO
END:VTOD
END:VCALENDA

Any help would be appreciated
