What are OST and MBOX files?

Every email client or any software that deals with data for that matter, uses a particular file for the storage purposes. OST and MBOX are such data files respectively for Windows Outlook and Mac Mail/Thunderbird. But there are plenty of differences between both of them.

The most important difference you need to know is this:

OST is short for offline storage table file used by Windows Outlook to store data in. It is implemented solely for the purpose of offline use. Outlook downloads your emails from the servers into an OST file (usually for IMAP and Exchange accounts). You can even work with your data when there’s no internet connection. And any changes you make into an offline mode gets synced to the servers when the connection is back up. This means that OST is just a form of a cached copy of your data from the servers. And this also means that OST isn’t meant to be used for backup, migration, import/export, or other similar purposes. It’s a basic, integral file that helps Outlook interacts with the data.

Also, OST cannot be used with other email applications. In fact, you can’t use manually OST with Outlook Windows itself by the ‘import’ function.

On the other hand, MBOX is a generic data file used by many email clients. You can use it to archive/backup your data. Or use it to migrate data to other email clients that identity MBOX format, such as Thunderbird. It was natively used by Mac Mail, but since then have become a standard extension relating to emails.

What Purpose does OST to MBOX Converter Serve

OST to MBOX converter does what they imply by their name – they convert OST to MBOX files. But why do that in the first place?

Since you are here looking for an OST to MBOX converter, you might already know. But let’s briefly review the objective behind the file conversion.

As already said, OST files cannot be used for basic data migration jobs for transferring your emails from Windows Outlook to other clients like Mac Mail or Thunderbird. But what if you do have OST files that you need to access the data from. In that situation, you can convert them to MBOX and then import MBOX to the client you are using.

This gets the inaccessible data from OST files imported easily.

But the process of conversion itself isn’t that easy or straightforward, especially if you are using an ordinary tool that isn’t built with proper consideration to all the complexities involved in the process.
