could I know the difference between mailbox ID and zimbra account ID .
I have another question
when a user is retired ,I made a full backup for the account then get the full label & his zimbra account ID then keep it in excel file in case we need to restore his mail again.
when I try to get a zimbra account ID for a user I couldn't find it in the accounts.xml file located in /opt/zimbra/backup
another question is there a retention policy for deleted mailbox
how can I know it
