Setting mailbox rights for Exchange 2007

Setting mailbox rights for Exchange 2007

Hi, the 'Set mailbox rights' screen allows permissions to be assigned to a user but it it states on the sceen that it 'Applies to...Exchange 2003'. ( http://www.manageengine.com/products/ad-manager/images/set-mailbox-rights.gif
 
I want to give someone READ permissions to a mailbox on an exchange 2007. Can this be done?
