About this app
Open Winmail.dat with just a tap. ABOUT A winmail.dat file is an email from Microsoft Outlook that can not be read by other email applications. It needs to be converted for the content to be accessible. Letter Opener does that with a simple tap! With over 10 years experience (and a special dislike for winmail.dat files) we made sure that working together with Microsoft Outlook and Windows users can be simple and seamless. FEATURES - Open Winmail.dat files and convert appointments, notes, contacts etc. to iOS native formats. - Get access to all attachments in Winmail.dat files. - Export files to another app. IN-APP PURCHASES - Winmail.dat Premium: Access to attachments in winmail.dat files SUPPORT We provide direct personal support, so don’t hesitate to contact us if you have any questions or comments: support@winmail.help Thanks for helping us to keep improving Letter Opener!
