I have a few old Outlook PST files that contain archived emails, attachments, contacts, calendars, and other mailbox data. I need to check the contents of these files, but I don’t want to install or configure Microsoft Outlook just to view them.
I was looking for a simple PST viewer that would allow me to open a PST file, scan its contents, and browse through the available folders and emails without modifying the original file. During my research, I came across SysInfo PST Viewer, which is designed to open and view Outlook PST files without requiring an Outlook installation or account.
The tool provides options to preview mailbox items such as emails, attachments, contacts, calendars, tasks, notes, and folders. This seems useful for checking archived PST files before deciding whether the data needs to be converted, recovered, or migrated.
