I recommend using the
MailConverterTools PST Viewer to view and
open PST files without Outlook. The software does not require the Outlook application to open, view, or read PST files. Additionally, it supports PST files from all Outlook versions. You can open password-protected PST files, even if you're unable to recover them. Moreover, this tool has no size limitations, allowing you to open large PST files and view corrupt PST files without any data loss.
