I’ve also used <STRONG>SysTools PST Viewer</STRONG> for this kind of task—it lets you open and preview mailbox data such as emails, attachments, contacts, calendars, and folders without setting up Outlook. For occasional viewing, that can be more convenient than installing Outlook just to inspect a PST.</P><P>&nbsp;</P> Tue, 01 Sep 2026 06:02:38 GMT picture_16 2026-09-01T06:02:38Z https://connect.mozilla.org/t5/discussions/what-is-the-easiest-way-to-preview-pst-files-without-outlook/m-p/135380#M54511 <P class=""><SPAN>A dedicated PST Viewer can be a practical option if you only need to inspect the contents of a PST without installing Outlook.</SPAN></P><P><SPAN>I’ve used </SPAN>SysInfo PST Viewer<SPAN> for this purpose.
