Hi,

Does anyone know how to generate a vCalendar or iCalendar email message like Outlook does? These messages are handled differently by Outlook when they arrive - Outlook shows an "Accept" button at the top of the email, and you only click on this button to add the appointment to your Outlook calendar.

We tried putting the vCalendar data into a body of a plain email message, but Outlook does not recognize this as a vCalendar invitation and shows the plain text:

BEGIN:VCALENDAR
PRODID:-//Microsoft Corporation//Outlook MIMEDIR//EN VERSION:1.0 BEGIN:VEVENT DTSTART:19980114T210000Z DTEND:19980114T230000Z LOCATION:My office CATEGORIES:Business DESCRIPTION;ENCODING=QUOTED-PRINTABLE:This is a note associated with the meeting=0D=0A SUMMARY:Meeting to discuss salaries
PRIORITY:3
END:VEVENT
END:VCALENDAR

We were able to include the appointment invitation as an ics file attachment though, but this requires users to open the file attachment, and does not generate the nice "Accept" bar at the top.

I'm guessing something needs to be done with the header of the email to get Outlook to recognize the vCalendar invitation. However, we were not able to view the source of the email message to see how it's done.

TIA
