I really thank the eSoftTools OST to EML Converter tool for convert OST to EML format. This tool gives accurate results without losing internal data. It can recover all email items, drafts, sent items, appointments, notes, journals, tasks with all email properties like to, cc, bcc, subject, etc. it can also convert OST files into multiple formats such as PST, EML, EMLX, Gmail, Office 365, vCard, MBOX, MSG, HTML, etc. t’s based on a GUI window which can make it easiest to use. Users can download a free demo file to convert OST files.
