"I like this Outlook viewer: it's simple and does what it should. It's sortable, so I can tune the list of emails to my needs. With the ability to convert emails to EML it seems even more powerful than the paid competitors."
Christian Crawley
"I downloaded Outlook Viewer and attempted to open several PST files that were generated from an email archive system. It worked like a charm - and the best thing about it is the zero price!"
