Overview

What Is PST to MSG Conversion?

PST to MSG conversion takes a Microsoft Outlook PST file and exports each email as an individual .msg file. MSG is Microsoft's native format for a single Outlook message — the same format Outlook uses when you "Save As" an email. Recipients with Outlook can open .msg files directly without importing a full PST. Converting to MSG is ideal for sharing specific emails with Outlook users or archiving messages in native Outlook format.

Our free PST to MSG converter processes on your device. You drop one or more .pst files, and the tool extracts all emails (including recovered deleted items when possible), then generates one .msg per message. All processing happens on your device; nothing is uploaded to any server.

Use cases include sharing with Outlook users — send a single .msg instead of a whole PST — moving important emails to another Outlook profile, legal or compliance archiving in native format, and backing up selected messages as standalone .msg files. No Microsoft Outlook installation is required to run the converter; it works on Windows, Mac, and Linux on any modern platform.
