To open orphan OST files without MS Outlook, you can use the SysInfo OST File Viewer. This free tool lets you view emails, contacts, and other data in OST files without needing Outlook or Exchange Server. Just download the tool, select the OST files, and view or export the data to formats like PST or PDF. It works with all Windows versions and supports OST files from any Outlook version.
