Extracts subject, sender, body, and embedded attachments into an open, cross-platform RFC 822 standard email compatible with Apple Mail, Thunderbird, and Gmail.
The Microsoft Outlook .MSG format is a proprietary Compound File Binary Format (CFBF/OLE2) designed specifically for Windows Outlook. Other operating systems (macOS, Linux, iOS, Android) and modern mail clients cannot open .MSG files without specialized third-party software. Converting .MSG into RFC 822 .EML translates the message into the universal open internet standard, readable by Apple Mail, Mozilla Thunderbird, Windows Mail, and webmail clients worldwide.
Select your Microsoft Outlook .msg message.
The engine parses MAPI streams and compiles an RFC 822 structure.
Save your standardized .eml file with all attachments preserved.
