Introduction to MBOX and PST formats

MBOX is a simple file format for storing email on the system’s hard drive. This is the basic file format supported by various e-mail clients (such as Mozilla Thunderbird, Sea Monkey, Eudora, Entourage, Apple Mail, etc.). These are the most common and widely used email clients. More than 25 e-mail clients actually support the MBOX file format.

Although MS Outlook is the most reliable e-mail client, it is widely used by users of famous Microsoft companies. It mainly supports two file formats, OST and PST. MS Outlook mainly supports the PST file format.

Therefore, several e-mail clients support the MBOX file format, but Outlook does not support the MBOX file format, but Outlook also supports PST and OST file formats and does not support the MBOX format. To open the MBOX format in MS Outlook 2019, users need to convert the MBOX file to PST format, which can then be easily imported into MS Outlook.
