Using the SysInfo OST Viewer is an easy way to open and view OST files without Outlook. The software allows you to load one or many OST files at the same time. You can see all the messages, attachments, and other data without requiring Outlook. It’s a perfect solution if you're unable to open OST files in Outlook and want to read or access the data from your OST file without any extra software.
