How to set up rules for shared mailbox in Exchange 2013?

Exchange 2013 provides the ability to set up shared mailboxes. How can rules (e.g. for sorting inbound mail automatically) be managed for these shared mailboxes? With earlier versions of Exchange, it was possible to log in to the shared mailbox with Outlook, and set up the rules there. The new Exchange 2013 shared mailboxes cannot be logged into. Does this mean that rules cannot be defined for shared mailboxes anymore?

from technet: "Shared mailboxes are a type of user mailbox that don’t have their own user name and password, so users can’t log into it them directly."
