I tried the MSOutlookHelp PST File Viewer last week and was truly impressed. The feature I appreciated the most was its ability to open PST files without needing Outlook to be installed—this was particularly useful since I no longer use Outlook. Additionally, it displayed attachments along with emails, so I didn’t have to open or install anything separately. The setup process was straightforward, it was so simple that I did it on my own without any technical assistance. Furthermore, it performed well on my Windows 10 laptop and is compatible with all versions of the Windows operating system.
