Archive Mailbox Not Visible in Exchange 2010

We used Exchange 2010 at work wherein each of the employees has their own mailbox and archive mailbox. I also used Exchange 2010 when I’m at home and I already configured my account at work with my account at home. However, when I’m at home my mailbox is visible while my archive mailbox is not. How can I make my archive mailbox at home visible? Help please.
