This app purpose is to show a chronologically ordered set of .msg files and, obviously, be able to read those mails (MS Outlook e-mails files ordered by their sent/received date in spite of file system date).

The problem that it solves is the following: when you export MS Outlook mails and move them between different kinds of media, the date they present is the file system created/modified date. Unless you import them to MS Outlook again, or to an equivalent app, there's no trivial way to re-order them again properly. This app permits you to do it easily in an Android environment: simply select files and/or folders where you have those .msg files stored and they will appear ordered by their sent/received date.

The free version only let you load up to 5 .msg files, does not save the e-mail listing between app restarts, only lets you open one mail attachment (the first one) and has ads.
