Working on a Mac, I often come across users and clients who need to shift their email data from Apple Mail to Outlook. The biggest issue? Apple Mail and Outlook don't speak the same language when it comes to file formats. Thus if you are asking, “how to open Mac Mail to PST on Mac OS?” You are already on the correct path — but just knowing the “what” isn’t enough. You need a complete, reliable method to convert Mac Mail files into PST format. Here's a practical guide based on my own experience using the Apple Mail to PST Converter for Mac.
Mac Mail stores its messages in MBOX file format, which isn't compatible with Microsoft Outlook. To access your Apple Mail emails in Outlook, especially for migration or backup purposes, converting them to PST is essential. The Apple Mail to PST Converter for Mac is a trusted tool that makes this process fast and accurate. With just a few clicks, you can convert entire mailboxes and keep your original folder structure intact. This guide breaks down the basics and provides a step-by-step solution for converting Mac Mail to PST format on Mac.
What Is Mac Mail?
Mac Mail, also known as Apple Mail, is the default email application for macOS. It’s a lightweight, built-in client that supports multiple email accounts (IMAP/POP/Exchange) and stores messages in MBOX format by default. It's ideal for daily personal or business use if you’re staying within the Apple ecosystem.
But when switching to Outlook, sharing data across platforms, or archiving emails in a format that’s widely supported, Mac Mail’s default format falls short — that’s where PST comes in.
What Is a PST File?
Personal Storage Table (PST) is a proprietary format utilized by MS Outlook. It can store a complete archive of emails, calendars, contacts, tasks, and more. What makes PST valuable is its portability — you can move it between systems, back it up, or import it into any Outlook version on either Windows or Mac.
Outlook doesn’t accept MBOX files directly, which is why the conversion from Mac Mail to PST is necessary when migrating.
Reasons to Convert Mac Mail Mailbox Data into Outlook PST?
- Creating a long-term, Outlook-compatible backup
- Sending email archives to colleagues who use MS Outlook
- Migrating to a new job or company system that runs Microsoft Outlook
- Accessing old mailboxes on a new platform
