What Should I Use to Open an Old Outlook PST File?

[Himanshu Sharma]

An old Outlook PST file can be opened easily with a dedicated 
viewer when Microsoft Outlook is unavailable. A dedicated PST 
Viewer allows users to access and preview stored emails, 
contacts, calendars, and attachments without installing Outlook. 
It is useful for examining archived PST files, locating specific 
mailbox data, and verifying contents before further processing, 
while keeping the original PST unchanged during inspection.
