About Converting MSG to EML
MSG is the proprietary container Outlook writes when you drag a message to disk. It preserves Outlook-specific data that plain EML cannot — categories, flags, voting buttons and calendar particulars — inside a Microsoft compound file. When you need to move away from MSG, the usual reason is simple: proprietary, poorly supported outside outlook.
Converting your MSG email message to EML solves that. An EML file is a single email saved exactly as it travelled: headers, body and MIME attachments in the plain-text format defined by RFC 5322. Because it is the wire format itself, almost every mail client can open one. In practice you gain open standard readable by nearly every mail client and preserves full headers, useful for audit and forensics. PrivConvert runs the whole MSG-to-EML conversion in server memory and deletes your file the instant the EML is ready — nothing is stored, logged or reused.
When this conversion helps
- You need open standard readable by nearly every mail client
- You need preserves full headers, useful for audit and forensics
- You need plain text, so greppable and archivable
- Reworking a fixed MSG file back into an editable EML document
- Escaping a proprietary MSG file for the open EML standard
Tips for best results
- After converting, open the EML and skim the formatting — complex layouts occasionally need a small touch-up.
- Files up to 250 MB are supported, and you can batch-convert several MSG files at once; each is processed privately and deleted immediately.
