An MBOX file is a mailbox format used by email clients like Mozilla Thunderbird, Apple Mail, Eudora, SeaMonkey, and several Unix based systems and stores all emails in a single text-based file.

Important Things to Know Before Converting MBOX to PST
Before we jump into any method there are a few critical things which you should understand. In my recent testing most conversion problems didn’t happen because of the tool but they happened because users skipped preparation. Keep the following points in mind
