Overview

What Is EDB to MBOX Conversion?

EDB to MBOX conversion takes a Microsoft Exchange EDB file (ESE database) and exports extracted email content into a single .mbox file. MBOX is a standard format that stores many messages in one file with a \"From \" separator. Thunderbird, Apple Mail, and Gmail use MBOX. Converting to MBOX is ideal for recovering Exchange mail when the server is down or for migration to another platform.

Our free EDB to MBOX converter processes on your device. You drop an .edb file, and the tool extracts readable emails and writes them into one MBOX file. All processing happens on your device; nothing is uploaded.

Use cases include Exchange recovery, migration to Thunderbird or Apple Mail, importing into Gmail or Office 365, and keeping one file per mailbox for backup. No Exchange Server is required — the tool works on any modern platform.
