Yes, a PST file can be converted without installing Outlook if a standalone PST Converter is used. Manual methods usually depend on Outlook, so they are not useful when Outlook is not installed, damaged, or inaccessible. For this situation, Trustvare PST Converter is a practical option because it can open orphan PST files and export mailbox data into formats like PDF, EML, MSG, MBOX, HTML, MHTML, EMLX, and TGZ. The tool also shows a preview of emails before conversion, which helps check folders and selected items before saving. It supports ANSI, Unicode, encrypted, and password-protected PST files. Emails, attachments, contacts, calendars, notes, tasks, and folder structure remain preserved during export. For testing, the free demo version allows saving 10 items from each folder.
