Send as other mailbox in Outlook 2007/Exchange 2010

I have added full access and send as permissions to a user in Exchange 2010.
The client is using Outlook 2007.

When the client next opens outlook, the additonal mailboxes appear.
However they cannot select which mailbox to send from.

How do you make the "From" field appear in Outlook 2007?

That easy hey! Thanks for that.
Anyway I can make it default to the users main mailbox so they don't have to enter their mailbox each time for the 99% of the emails they send normally?

You can also sending from "addtional mailbox" using OWA. The user must log using their personal credential. To log thru OWA.
