Hi, I need to restore a calendar file from an ICS that I exported from a recovered account. I am running this command as the zimbra user ( and I have done this with success in the past). I am running 4.5.11. Last time I ran this successfully, I was probably at a different version. My command and output is below. Any advice?

$ zmmailbox -z -m username@domain.com pru /Calendar /tmp/userrestored.ics
