There are several options available in the market, but I will suggest that you try the TrustVare PST to PDF Converter Tool, the least expensive option to batch convert PST files into PDF file format with attachments. The software provides functionality to the user to save the Outlook emails to an Adobe PDF format and take PST files and print it to a PDF. In addition, the utility provides the user with a confirmation that the PST data is converted to the PDF for their validation. The utility is fully compatible with the PST files as created in any version of Outlook, i.e., Outlook 2021, 2019, 2016, 2013, 2010, 2007, and any older versions. In the free demo of the utility, the user is provided with the capability to convert some of the first items from PST file format to PDF format.
