What is the difference between vcalendar and icalendar? Is it only the VERSION difference as 1.0 and 2.0 respectively?
For sending a Meeting Request with iCalendar and vcalendar, I specify the MIME type as text/calendar.
The email sent with iCalendar appears as a Meeting Request while the one with vCalendar appears as an attachment. When I double click the attachment, it opens up as an Appointment.
