Winmail.dat contains all attachments and rich text message, and not all e-mail clients can recognize its format. There is the solution. Winmail Viewer Pro Edition is just the tool for the job. This app allows users to open .dat folders and to view, extract, share and save all contents. With Winmail Viewer Pro Edition’s user-friendly interface, anyone can overcome this frustrating technical issue in a matter of clicks. In addition, it also supports batch extraction of Winmail.dat files directly into Download folder.
