You are searching a tool for Postbox to Outlook PST then I would like to suggest MailsDaddy MBOX to PST converter. This is the best GUI based application that easily migrates the entire mailbox to Outlook. If you want to use this solution then you have to use Window OS because the tool supports only window operating system. After conversion, you can import resultant PST into MAC OS. The tool has many outstanding features like email filter, save , preview, multiple export etc. Not only this, rather you can use this tool on all MBOX, MBS and MBX based email clients data including Postbox.
