I have an orphaned OST file from my old Outlook profile, and I need to convert several emails into MSG format. Before starting the conversion, I want to preview the emails inside the OST file so I can choose which ones to export. Is there any safe method or tool that allows me to view OST emails without Outlook and then export selected items to MSG? I am worried about data loss, so a reliable solution would be helpful. What are the best ways to preview OST emails before converting them to MSG?
