We have been using vcalendar for a while now. Recently after upgrading to outlook 2007 from 2003 when I double click to open the .ics file when it opens, I have a To: field at the top and a Send Update button to the left instead of Send. I assume this is because it sees it as an existing meeting rather than a new appointment.Any idea???In case it helps, here's what I get in Notepad from the .ics file:BEGIN:VCALENDAR
