How to Convert Apple Mail to Outlook?

Personal Storage Table (PST) File is an Outlook data file that can be easily imported into Outlook for Windows. And so, MBOX to PST conversion is the most reliable way to move emails and other mail items from Apple Mail to Outlook PST. Apple Mail (also called Mac Mail or simply Mail) is the default email client for MacOS. It stores all the mailbox data in an MBOX file format. However, the MBOX file is not supported by Microsoft Outlook. Thus, if you want to access Apple Mail (MBOX) to Outlook, you will need to convert MBOX file to PST file format.

Before we discuss the methods to perform the conversion, let’s first discuss why it is needed.

Situations that may call for converting Apple Mail data file to Outlook data file are as follows:

  • For migrating data from Mac to Windows platform.
