Converting Outlook PST files without Outlook is possible with a dedicated Outlook PST Converter. Manual options usually depend on Outlook installation and may not be useful when the system does not have a configured Outlook profile.

For this type of task, Softaken PST Mailbox Converter can be considered because it works without Microsoft Outlook and exports PST mailbox data into multiple formats. It supports formats like MBOX, EML, EMLX, MSG, PDF, HTML, MHTML, VCF, CSV, TGZ, NSF, and IMAP-supported options.

The software also previews mailbox folders before export, which helps check emails, contacts, calendars, and attachments before conversion. It supports ANSI and Unicode PST files and can save output at the selected location. For testing, the demo version allows exporting up to 25 items.
