PST and MBOX Format – Overview
Before we move on to the process of converting PST to MBOX, we first need to have a quick understanding of what PST and MBOX are.
PST: – It is a file type compatible with Outlook which it uses to store users’ data locally. PST (Personal Storage Table), has the ability to hold the entire mailbox of an email profile along with various mail folders, contacts, calendars, and other stuff. Additionally, the PST file type also serves as a medium for sharing information, so users use it to create backups of their data.
MBOX: -It is also a file type for storing email profile data locally, but not for Outlook. It only works for saving emails with their relevant details (including attachments). An MBOX file can contain a mail folder with all the internal available email items. It doesn’t work in Outlook, but there are about 50+ email applications which supports MBOX format.
Why Convert Outlook PST to MBOX?
There are several reasons why users might want to convert PST files to MBOX:
- Moving Emails to Different Email Platform: – PST files only work in Outlook, so users who want to access their emails available in a PST file must convert PST to MBOX. This enables users to access Outlook emails and transfer them to email clients that support MBOX files.
- Creating Backup of Outlook Emails: – Users create backup of Outlook emails by converting PST to MBOX. Apart from the PST file, keeping an additional backup of Outlook emails as MBOX can help users in several situations. These cases can be deletion of PST file from user’s drive, accidental deletion of emails from PST, corruption in PST, etc.
- Separately saving each Outlook Mail Folder: – PST files contain a collection of mail folders, which makes it difficult for some users to quickly access the emails they need. Therefore, some users prefer to extract mail folders from PST and save each mail folder as a separate MBOX. This makes it easier for users to manage mail folders easily.
