Export Mac mail into Microsoft Outlook manually

MBOX is a file format which is supported by Thunderbird, Apple Mail, and Mozilla email clients to store email files in a Windows based Operating System. 

PST (Personal Storage Table) is the file format supported by Microsoft Outlook to store the email files. Most versions of Microsoft Office include the Outlook application which can also be used for email communication. It is also available as a standalone purchase for desktops. 

Thunderbird is the open source "free" application that is also supported in Windows, Linux, and Mac OS. Many users find Microsoft Outlook to be more interactive and secure when compared to other email clients. Outlook comes with regular updates (both free and paid) as well as a wide range of useful add-ons. 

These are prime reasons why many users are more inclined to switch to using Outlook for their email needs. There is no doubt many more reasons to switch from Apple Mail over to Outlook, but below I will share some of the more common reasons for migrating from an Apple Mail "MBOX" format, over to Outlook "PST" format.
