But then it won't be identified as an ICS file anymore by automated processors.  The "Content-Type" matters.

    Calendar.SaveToFile(CalendarFile);

You don't need to duplicate the calendar data like that.  I would populate just the Calendar object and then Assign() it to idTextPart.Body.  Or get rid of the Calendar object and call idTextPart.Body.SaveToFile().

On the other hand, you don't need a temp file at all if you use TIdAttachmentMemory instead of TIdAttachmentFile.

    Attachment.FileName := CalendarFile;

You are missing the 'method' attribute again on the ContentType.  That attribute is REQUIRED by RFC 6047 Section 2.4.
