About
Got a winmail.dat instead of the PDF you were promised? An Outlook .msg your iPhone won't open? MailFolio opens it and hands you what's inside: the attachments, the formatted message, the meeting invite. Everything is processed on your device.
SUPPORTED FORMATS
• Outlook MSG and OFT
• EML and EMLX messages
• MBOX mail archives
• MHT and MHTML web archives
• Winmail.dat / TNEF attachments
BUILT FOR REAL CORRESPONDENCE
Read formatted HTML, plain text and compressed RTF content. Inspect sender, recipients, dates and message headers. Preview, save and share attachments with Apple’s native tools. Search a message, reply or forward, and return to recent files in your private local library.
MORE THAN THE MESSAGE
• Quick Look previews of MSG, EML, MHT and Winmail.dat in Files and Finder
• Outlook RTF messages keep their formatting
• Meeting invitations and contact cards as readable cards, with Add to Calendar and Add to Contacts
• Outlook meeting requests show their time and location
• Emails attached to emails open right in the reader
• Large MBOX archives and Apple Mail .mbox folders
• S/MIME-signed messages open normally; links open in your browser only after you confirm
EXPORT WITHOUT A CONVERSION SERVER
Create PDF, EML, HTML or plain-text copies for sharing, filing and reference. Your messages and attachments are processed on your device—not uploaded to MailFolio. Remote email resources, scripts and forms stay blocked while you read.
