How to Convert PST to Apple Mail
Apple Mail and Outlook perform the task of managing your email in a similar manner. However, the file formats used to store your contacts and messages in the two programs differ considerably. The Mac mail program does not offer native support for importing Outlook PST files into Apple Mail directly, but several commercial apps are available for this purpose. If you want to import your Outlook contacts and messages into Apple Mail without having to purchase an expensive third-party app, you can use the free Thunderbird email client as a go-between for the mail programs.
