PST to PDF Converter: frequently asked questions

All 8 technical & workflow FAQs
Can I convert PST files to PDF without installing Microsoft Outlook?

Yes. Prism PST to PDF Converter features an autonomous B-Tree parser that extracts email data directly from PST files without requiring Outlook, MAPI DLLs, or Exchange Server.

What are the 5 PDF layout styles and how do they differ?

The software includes 5 specialized layout styles: (1) Standard Card Layout: Modern email presentation with high-contrast sender badges and structured typography; (2) Compact Grid Header: Two-column grid layout designed to minimize header space; (3) Classic Email Archive: Traditional Outlook-style top header block; (4) Minimalist Clean Text: Distraction-free, clean layout focusing on message body; (5) Detailed Metadata Header: Comprehensive box showing Message-ID, Sender Address, Priority, and Flags.

How are email attachments preserved during PDF conversion?

The software offers 3 attachment strategies: you can embed binary attachments directly inside the PDF container using standard embedded file dictionaries, extract attachments into a dedicated companion folder next to the output PDF, or omit attachments for lightweight archiving.

How does Bates and page numbering work in the output PDF?

When the 'Add Bates / Page Numbers' option is enabled, the converter automatically stamps a standardized footer on every generated page combining dynamic page counts and sequential Bates identifiers (e.g., 'Page 1 of 5 Bates #PST-00001').

Can I combine all emails into a single PDF file instead of separate files?

Yes. In Step 4 Document Generation Mode, you can choose between 'Individual File per Email (One file per message)' or 'Single Combined File per Folder' to merge all messages in a mailbox folder into a consolidated PDF archive.

Can I preview my PDF layout before running the export?

Yes. Step 4 features a live interactive virtual document preview canvas that dynamically reflects layout design styles, page orientation (Portrait or Landscape), and active email header fields in real time.

Can I choose which email headers appear on the PDF page?

Yes. You can individually toggle Subject, From, To, Date, CC/BCC, and Body content using interactive chips, with one-click presets for All, None, or Standard configurations.

What happens if my conversion process is interrupted?

The integrated SQLite transaction checkpointing records every processed message in the migration_progress table. When you restart the application, the Resume Center will automatically detect incomplete sessions and continue from where it stopped without duplicating items.
