In this digital day and age, emails have become the go-to form of communication within the corporate world. They may be more of a hassle than regular text messaging, but they maintain a sense of decorum that companies worldwide cherish. An MBOX file comes in handy in such situations. An MBOX file is a concatenated list of all the messages in an inbox, in the form of a single text file. But you cannot open an MBOX file in Outlook as it does not support the MBOX file format. To counter this, you need a mbox to pst converter, as PST is a supported file format in Outlook. 

Having said that, some compatibility issues hinder the experience from becoming truly seamless. There is a wide range of email clients to choose from, and every company or individual selects the client that suits their needs the most. But every email client has its particular file format, and one email client will not be able to open files from another. This article will give you a step-by-step guide on how to open .mbox file in Outlook, starting by showing you how to convert it to PST format. 

Converting MBOX Files To PST

MBOX compatibility issues can occur anywhere at any time for a corporation or individual who uses Outlook as its default email client. For example, if someone sends you an MBOX file from an email client that supports it and you are using Outlook, which does not, you will not be able to open it. 

This issue can also rear its head when the corporation or individual switches from one email client which supports MBOX files to Outlook and wants to import their mailbox. To solve these problems, you need to first convert the .mbox file to PST, which is a file format supported by Outlook.
