Are you an Outlook user and want to extract messages from Outlook .pst file to MBOX format so that you can easily access them in any email client that supports MBOX format like Thunderbird, Apple Mail, Entourage, Opera Mail, Evolution, Spicebird, Netscape, Postbox and many more.

Reasons for Converting data from PST to MBOX

Reasons for moving PST files to MBOX vary from user to user, but the most common among them are as follows :

Change in job environment

When users shifts their job, they need to work in accordance with the new office environment. It requires them to change their previous email client (Outlook) with the new one too (Thunderbird, Apple Mail, The Bat! Etc.). But during the process, they don't need to lose their important emails that they have within their previous email client. So they want all their previous email data in current email client and thus need to export PST as MBOX.

Shifting from Windows Platform to Mac Platform

When users decides to change their operating system, they'll need to transfer all the data from machine to the another. And this includes emails too. Taking a backup will only save the emails on the new system, but to view them, they need to be converted into a file format that is compatible with the new machine's email client. So, to view and open Outlook's emails (.pst) in Apple Mail, they are required to be converted into MBOX format.

PST Files are more susceptible to Corruption

Once a PST file reaches its maximum data storage limit, it becomes more likely to be corrupted and may create problems while users try to view it in Outlook. So, users look for alternate ways to view their emails in some other application (by converting PST files to MBOX), where there is no such problem.

Remote Access to PST Files is Not possible

Once an Outlook email is saved or archived into a PST file, it becomes impossible to remotely access it on any other application like Outlook Web Applications, smartphones etc. which automatically synchronize with your account. Reason being non availability of PST file on server as it will be saved on your local machine.
