If you want to open or import OST files into Outlook the direct method won’t work because Outlook only supports PST files for import. The best and most reliable solution is to use DataVare OST to PST Converter. It quickly converts your OST files into PST format without data loss including emails, attachments, contacts, calendars and more. Once the OST is converted to PST you can easily import it into any version of Outlook 2019, 2016, 2013, etc. The software is user-friendly, safe and gives 100% accuracy. I’ve used it personally and it works for both small and large OST files.
