Find An Effortless and Reliable Conversion Solution to Switch from PST to MBOX

When comparing MS Outlook with any other email clients, MS Outlook has no match because it is more than an email client. A PST file can store not only emails but also Tasks, Contacts, Events, and Journals. The file storage limit can stretch to up to 50 GB which means huge storage. But when it comes to comparing the app for flexibility and compatibility, Outlook doesn’t allow users to share its data to other email platforms. PST is an internal Outlook format. Therefore, for accessing PST files to a range of email platforms, the best way is the conversion of PST files. The MBOX file extension holds emails and their properties. It is used by several popular email apps like Thunderbird, Apple Mail, Postbox, PocoMail, and name a few. Talking about the reasons for conversion, one reason we have already mentioned above. Another reason is that Outlook is a paid program, but MBOX supports free email clients. Moreover, MS Outlook is a complex program as it is more than an email client as it lets you organize tasks, calendars, and many more. Several users who want to use an email client personally don’t need all these features. It can also lead to conversion.
