Before migrating an old PST file, I think it is important to check what data it actually contains. Older PST files may include years of emails, attachments, contacts, calendars, tasks, and multiple folders, so manually checking everything can take a lot of time.
I was looking for a way to preview an old PST file without changing the original data. A PST viewer seems useful for this because it can scan the file and allow users to browse its contents before deciding whether the data needs to be migrated or converted.
SysInfo PST Viewer can be used to open and examine PST files and preview mailbox items such as emails, attachments, contacts, calendars, tasks, and folders. The basic process is straightforward: select the PST file, scan it, and browse the available mailbox data. This can be particularly helpful when working with old archives or backup PST files and you are not sure what information they contain.
