Yes, I do see some mention of the event in mailbox.log (below). However, it's not very telling. It would be great to know that my ICS file didn't parse because of a certain line. I see authentication failures (not in this event) offer a java trace in mailbox.log. Can I conclude that REST believes it had no errors when processing my ICS file if there's nothing in mailbox.log?
