zimbra mailbox purge

[rajeshkodali]

I have a problem that a mail box has been purged and we don't know how it happed I could see the purge log /opt/zimbra/mailbox.log.*
1. we are around 5 admins and all of us have admin rights in zimbra admin console, I would like to know how can I know who has deleted it.
2. Is there any log to see who has logged in admin console
