The result was that the invitation noticed inside the calendar only first event, the second was omitted.
What was wrong?
I observed the same result in Outlook and Gmail.

if you want to import many events :
To gmail , you could implement the api of gmail calendar ,
To outlook , you can alter the icalendar method to "publish" , and it would create new calendar , the new calendar will include many events
if you send just an appointment , that would not be a problem , but if you have many appointments, it would be a problem , because its weird if you include many events in an email or you send per appointment per mail
