"The Coolutils Mbox Viewer allows you to view MBOX in a decently quick fashion. We use it to view archived clients' emails and it works just fine. My only recomendation is to change the default action for attachments. Now the program tries to save it if I click on the attachment and I'd like it to open the attachment first. Thank you!"
Martin Nielson, Legal Secretary
