What is a EMLX file?

EMLX is Apple Mail's proprietary format for storing individual email messages on macOS. Each email in Apple Mail is saved as a separate .emlx file in the Mail directory.

EMLX characteristics:
- Apple-only format — used exclusively by macOS Mail (Apple Mail)
- One file per email — similar to EML but with Apple-specific metadata
- Hidden in Library — stored in `~/Library/Mail/V*/` (hidden by default)
- Contains XML plist metadata — Apple appends metadata after the MIME message

Where to find your EMLX files:
- Open Finder > Go > Go to Folder
- Type `~/Library/Mail/`
- Navigate through `V9/` (or current version) > your account > mailbox folders
- Each `.emlx` file is a single email

EMLX files cannot be opened by Outlook, Thunderbird, or other non-Apple mail clients without conversion.

What is a PST file?

PST (Personal Storage Table) is Microsoft Outlook's standard format for email storage and archiving. Converting your Apple Mail emails to PST format allows you to access them in Outlook on Windows.

PST advantages for Apple Mail migration:
- Open in Outlook — immediate access to all your emails on Windows
- Organized structure — EMLX files scattered across directories become organized folders in PST
- Single file — thousands of EMLX files become one manageable PST file
- Full metadata — dates, attachments, read status all preserved

Why convert EMLX to PST?

EMLX to PST conversion is essential when switching from Apple to Microsoft:

1. Migrating from Mac to Windows
Moving from macOS to Windows means your Apple Mail emails (EMLX) need to be converted to PST for Outlook. There's no native import path.

2. Switching from Apple Mail to Outlook
Even on Mac, if you're switching from Apple Mail to Outlook for Mac (which uses OLM/PST), you need to convert your EMLX archive.

3. Enterprise standardization
Companies with mixed Mac/Windows environments often standardize on Outlook. Converting EMLX archives ensures all email data is in the enterprise-standard PST format.

4. Archiving Apple Mail data
EMLX files are fragile (thousands of tiny files in hidden directories). Converting to a single PST creates a robust, portable backup.
