If you have stored your email data in PST (Personal Storage Table) and want to open PST file in Apple Mail, you have landed on the right page. Here, you will know all about opening PST files in Mac mail.

We know that Outlook's data storage file and portability make it a preferred choice for email users, but you can't open PST files directly on Apple Mail. But there are some ways in which you can open PST file in Apple Mail. We can do this by converting PST files to MBOX file format, but before knowing the conversion methods, let us first briefly discuss Apple Mail and Microsoft Outlook.

A Brief Intro to Microsoft Outlook

Outlook is an integral part of the Microsoft Office suite, which is very popular as a desktop-based email client and the web version. It functions as an email application and includes calendaring, journals, note-taking, task manager, contact manager, web browsing, security features, and more. Outlook uses OST and PST file formats to store data; OST is an Offline Storage Table stored in the system where Outlook is installed, while PST can be ported to any other local storage device. MS Outlook allows the user to export-import the PST file by an inbuilt option of Open/Export.

A Glance on Apple Mail

Apple Mail has a reputation in the email market due to its advanced features and offerings. It is the default mail client of Mac OS and iOS. Mac mail saves the file in MBOX file format, and users can easily import MBOX files and open them. MBOX is a widespread file format that many email clients are using.

However, MS Outlook has a vast user base; still, Mac Mail is becoming the first choice for users when it comes to choosing a futuristic email client. Both email clients are best at their place, but when an Outlook user migrates to an Apple Mail client, the user faces many problems because both email clients use different file formats. Outlook saves its files in PST format, and Mac Mail saves its data in MBOX format; hence, it is necessary to convert PST to MBOX file format to open PST file in Apple Mail.

Why User Move from Outlook Email to Apple Mail?

There are several reasons why a user migrates from an Outlook mail client to Mac mail. Some of the reasons are discussed below:

Migrating from Windows OS to Mac OS: Migration from Windows OS to Mac OS can also be considered an upgrade as per the market; Apple has become a status symbol. When a Windows OS user moves to a new Mac operating system, the user gets Apple Mail as the default email client.

High Management Cost: We all know that Outlook has very advanced features and is a paid email application too. Due to its daily advancement, its management cost is also rising, and Outlook users are switching to Mac mail.

Organization Upgradation: When an organization upgrades from Windows to the Mac Operating System, the employees have to access their Outlook data in Apple Mail and they search a way to open PST file in Apple Mail.

Migration to Another Organization: When a user moves to another organization where the company functions on the Mac operating system, the user needs to export mailbox data to MBOX format, which can easily be accessed in Apple Mail, and hence need to open PST in Apple Mail.

Practical Issues: We all face some issues with technology, and email clients are not an exception. Users face issues such as corruption of files, account deletion, hard drive crashes, etc. This problem sometimes forces the user to shift from Outlook to Apple Mail.
