Yes. MacSonik PST Viewer  is designed to handle large PST archive files without requiring Microsoft Outlook. It can open and analyze oversized PST files while allowing you to preview emails, attachments, contacts, calendars, and other mailbox data.
It also supports bulk PST analysis, advanced search filters, attachment filtering, folder hierarchy preservation, and selective export to formats such as PST, PDF, EML, MSG, MBOX, CSV, and Microsoft 365. For PST files larger than 45 GB, it can split the exported PST into smaller, manageable files.
