You can use the manual method to download attachments from the Outlook PST file. But the manual solution to download attachments from Outlook PST files is only for technical users who have good technical knowledge. According to me, you can use a professional tool like GainTools Outlook Extractor. It is easy to use for users, and there are no technical problems with it. With its help, all types of attachments like PST, PDF, DOC, and JPEG can be extracted from MSG files. You can easily download this tool on a Windows computer, and it works well with all versions of Outlook. You can extract attachments from some Outlook files for free with the demo version of the software.
