We're preparing to migrate our users from the Sun Java Calendar system to Zimbra. I am testing calendar migrations.

I was able to export my Sun calendar to a .ics file and then imported it into Zimbra using the information provided in the Wiki.

The events now appear in Zimbra, but when I right click these imported events I get this.

So the events all imported in a state where they haven't been confirmed/accepted. If I choose to OPEN, it just opens the event in a window but I can't edit it. If I choose to ACCEPT/DECLINE/TENTATIVE I get the following error.

I am not able to edit any of these imported events. Anyone know why?
