PST files from different Outlook versions can be viewed using a dedicated PST viewer that supports common Outlook data structures. Aryson PST Viewer allows users to open and examine PST files without installing Microsoft Outlook. It provides access to emails, contacts, calendars, and attachments stored in the mailbox. Users can load the required PST, browse folders, and preview available data without modifying the original file. This makes it useful for inspecting older or archived PST files created with different Outlook versions. Keeping the source PST unchanged during viewing also helps protect the original mailbox data while you verify its contents.
