I have found a previous thread on this issue, but it was a few years old and not very helpful. I wonder if anyone has any experience moving a calendar from one user's mail account to another. I'm sure you can imagine the scenario where this is required--where one account needs to be closed or locked and another person set to administer the calendar, but I cannot find any information on making such a change on a recent version of Zimbra (6.0.7+).
Any guesses? By the way, the calendar has multiple shares with other users, mostly viewers only. Thanks,
