Email migration from MBOX-based clients to Outlook or Office 365 often becomes difficult because data must stay intact while formats change. vMail MBOX Converter is built to make that move predictable, controlled, and less time-consuming, even for non-technical users.​

Why MBOX migration is tricky

MBOX is used by clients like Thunderbird and Apple Mail, but Outlook relies on PST, and Office 365 needs cloud import/migration methods, so direct “drag-and-drop” isn’t always possible.​
During migration, users typically worry about folder structure, attachments, and message properties getting altered or lost.​

How vMail MBOX Converter simplifies the job

vMail MBOX Converter is designed to convert MBOX data into Outlook-friendly PST and other common formats while keeping mailbox data organized.​
It supports converting MBOX into PST, EML, EMLX, MSG, HTML, PDF (as listed in product details), which helps when the goal is not only Outlook migration but also archiving and legal/compliance exports.​

Repair + conversion in one flow

A major advantage for real-world migrations is that the tool can scan and recover emails from corrupt or damaged MBOX files, restoring messages from accessible or inaccessible mailboxes.​
This reduces dependency on the source email client, behaving perfectly, which is a common blocker when old profiles or large mail stores are involved.​

Migration to Outlook and Office 365

For Outlook, the tool can convert recovered mailbox content into a healthy Outlook PST while maintaining email metadata such as To, CC, BCC, Subject, Date-Time, and attachments.​
For Microsoft 365, the software includes an email migration option to an Office 365 account (and also mentions Gmail/G Suite and Exchange Server), which is useful for organizations moving from local archives to cloud mailboxes.​

Features that improve accuracy and control

The software allows users to view each email without needing MS Outlook installed, which is helpful for verification before exporting or migrating.​
It also supports working with large MBOX files and can split output into multiple smaller PST files—useful when mailbox sizes are big or when PST size policies need to be respected.​
Additionally, it supports multiple Outlook versions (including Outlook 2021 and earlier versions listed), which helps teams with mixed desktop environments.​
