From: Howard Brazee on
I put in a leave request using a web application at work. It sent an
email with an attached .ics file to my work account which I clicked on
to make my Outlook accept it - and forwarded that e-mail to home and
clicked on it to put it in iCal.

Today the request was approved, so I decided to edit my iCal entry. I
don't know how. It has buttons for [Maybe], [Decline], & [Accept],
and will let me edit some features. But I want to make it an
ordinary meeting without buttons, and change the title from "Leave
request...".

Playing around, I got a window saying
There was an error with the invitation

Only the organizer can change the event. Cancel the organizer to
make changes.

I suppose I can delete it and start over. Is that my only option?
