I have several Outlook PST archives that contain important emails from previous projects. The information is useful for future reference, but keeping everything inside PST files isn't always convenient, particularly when I need to share specific conversations with colleagues or maintain records that can be opened without depending on Outlook.

For this reason, I started looking for a reliable way to convert PST to PDF in bulk instead of opening individual messages and saving them separately. With hundreds or thousands of emails, manual export quickly becomes impractical. I also wanted the converted documents to retain useful email information such as the sender, recipient, subject, date, and message content.

While comparing different solutions, I came across the SysInfo PST to PDF Converter. The feature that interested me most was its ability to handle single as well as multiple PST files. It also provides a preview of mailbox folders and email information before conversion, which seems helpful when working with old PST archives whose contents aren't clearly known.

Attachments are another important consideration. Some of my archived emails contain invoices, reports, and other documents that need to remain associated with the original messages. The software provides options for handling attachments, including converting them into PDF or saving them separately, depending on the user's requirement.

Another useful feature is duplicate filtering. Backup PST files can contain the same email several times, so exporting everything without checking duplicates can result in a messy archive. Filtering based on properties such as From, To, Subject, Bcc, and Body can help avoid unnecessary copies.

For anyone planning to convert PST file to PDF, I think it is worth checking the output structure and attachment options before processing a large archive. The ability to select specific mail folders and apply date-based filters can also be useful when only a particular period needs to be archived.

Has anyone here dealt with a large PST-to-PDF archiving project? I'd be interested to know whether you converted the complete mailbox or selected only the folders that were actually required.
