Immediate archive for specific mailbox

Hi People,

Does this KB article http://www.symantec.com/business/support/index?page=content&id=TECH66263 still applies for EV 9.0.4R1 ?

I need to do complete mailbox item archived every day for all the disabled user account in a specific OU, but somehow the mailbox that I have dropped in the custom OU that I created is not all archived.

Please assist me to achieve this before I delete the AD account and the mailbox from Exchange server that is almost full.

Thanks in advance.
