Winmail.dat Opener App

The winmail.dat file contains Rich Text Format information for the message but usually cannot be opened by the normal e-mail clients. Winmail.dat files are in fact called T.N.E.F. files (Transport Neutral Encapsulation Format). Microsoft Outlook e-mail for Windows send e-mails in TNEF format, but most other e-mail clients or applications do not understand TNEF. The app will extract the winmail.dat file on your device, then you can preview, resend or print or save them.
