Why Convert PST to MBOX? Benefits, Real-World Use Cases & Top 7 Solutions Compared

Introduction

The PST file (Personal Storage Table) is the file extension that Microsoft Outlook uses for the data of email messages, attachments, contacts, calendar entries, tasks, etc. in Outlook. Users prefer email clients like Thunderbird, Apple Mail, SeaMonkey and others rather than Microsoft Outlook as the number of email clients continues to grow globally. Certain aspects of the PST data file become difficult or impossible to access once a user moves away from Outlook email clients.

For Outlook users, it becomes necessary at a certain point to pay attention to the need to convert a PST file to MBOX file format. With this conversion, users acquire an opportunity to transfer their emails easily, create more compatibility with other compatible email clients and still be able to keep their important email information without being dependent on Outlook at all.

This article focuses on explaining why changing PST into MBOX is beneficial and important and what advantages are provided by PST to MBOX converters. It provides a comparison of complete solutions that can help users cope with their tasks as quickly as possible.

What Is a PST File?

The PST or Personal Storage Table file is a proprietary mailbox file developed by Microsoft that is used by Microsoft Outlook to store:

• Emails
• Contacts
• Calendars
• Tasks
• Notes
• Journals
• Attachments

PST files are usually used for storing personal mailbox information as well as for storing Outlook backups and archived data. As PST files are specifically developed for use in Microsoft Outlook, such files must usually be accessed only via Microsoft Outlook itself or other compatible software.

What Is an MBOX File?

MBOX files can be regarded as one of the most widely accepted mailbox formats embraced by a plethora of desktop email applications.

Some of the common email applications that support MBOX include:

• Mozilla Thunderbird
• Apple Mail
• SeaMonkey
• Eudora
• Opera Mail

MBOX is not restricted like PST and thus can be transferred from one OS or application to another without any difficulty.

What Does PST to MBOX Conversion Mean?

The transfer of Outlook mailbox data from the PST format into MBOX is termed PST to MBOX conversion and is done keeping the other data intact, like:

• Emails
• Folder structure
• Any attachments related to emails
• Who sent the email and who received the emails
• Email metadata
• The date and time of the sent emails

The objective is to allow Outlook emails to be accessed by the users of MBOX-supported email clients.

Why Do Users Convert PST to MBOX?

The reasons for users opting for migration from Microsoft Outlook to other email clients are many.

• Many users have moved to Thunderbird, Apple Mail, or Linux email clients which do not work with PST.
• MBOX format is more compatible and can be used with different operating systems and email applications.
• Organisations also use MBOX for archiving purposes as it is an open universal format.
• Instead of PST, MBOX is accessible on Windows and macOS.
• Migrating organisations perform conversion from PST to MBOX files before importing data into the new email accounts.

PST vs MBOX: Key Differences

Benefits of Converting PST to MBOX

The process of converting PST files seems to entail several benefits besides merely switching the format of a mailbox.

• One of the greatest advantages is that users can access their mailboxes from the supported email software without the need to have Microsoft Outlook installed on their computers.
• This means that MBOX can function with many of the most widely used desktop email software such as Thunderbird, which decreases the reliance on just one platform.
• Whatever the email software you would like to switch to, whether Outlook, Thunderbird, or Apple Mail, the conversion into MBOX will help you move the emails swiftly.
• As MBOX is a very universal format, it can be used for long-term storage of emails.
• Once the mailbox information is saved in the open format, new migrations will become easier in case user opt for changing their email software again.

Why MBOX Is Preferred by Many Email Users

• Works with various email softwares
• Offers easier migration options
• Accepted on many different platforms
• Ideal for email archival/backups
• Has less reliance on proprietary technology

For individuals who plan to migrate again, MBOX will allow them more freedom.
