If you want to convert your OST file to PDF so you can share your emails easily, using a dedicated converter is the simplest way to do it. FixVare OST to PDF Converter works well for this because it lets you open the OST file directly, even if Outlook isn’t working, and turn all your emails into clean PDF documents. The formatting, attachments, and folder structure stay the same after conversion, so everything looks just like it does in Outlook. Once the emails are saved as PDFs, you can share them without any compatibility issues since PDF opens on almost every device. I’ve used this tool before for sending email records, and it made the whole process straightforward.
