Email clients are excessively used for emailing purpose all around the world. You must be using an email client in your day-to-day life. While using any an email client application, you must be aware about the file format in which your emails and other mailbox content are stored. Generally, email clients don’t support same file format. Switching to a new email platform sometimes becomes challenging as you might not be having extensive knowledge of how to migrate mailbox content from one email client to another, especially when both the email clients support different file formats. In this post, we’ll discuss on one such email migration of MBOX to PST format.

The majority of email clients use MBOX file format to store email messages, such as: Thunderbird, Entourage, AppleMail, Netscape, Spicebird, PocoMail, Evolution, Opera Mail, IncrediMail, Claws Mail, Sylpheed, SeaMonkey, Mulberry, Eudora, etc. Email messages stored on MBOX file can easily be migrated from one email client to another only if both the email clients support MBOX file format. Unluckily, if you’re switching to Outlook client from any of the above email clients, email migration can’t be done without proper email conversion of MBOX to PST format. Microsoft Outlook doesn’t support MBOX file format, so you can’t access the email messages without exporting them into PST format. Even the built-in Import feature doesn’t import this file format into Outlook. Therefore, you must convert MBOX to PST format in order to transfer email messages from one of these applications to Outlook client.

MBOX aka email mailbox is an email storage file format that stores and organizes email messages in a single text file. All the email messages are saved in concatenated format, so that each email message can be stored after another.

PST aka personal storage table is an Outlook data file that stores personal information used by MS Outlook and Exchange Server which include email folders, contacts, calendars and other mailbox data.
