In addition, I am looking to create simple HTML page to present to the
users. Page (if it is possible) is going to be splitted in two windows
(?), one window will have a Outlook folder with e-mails and another is
a preview pane. This functionality is a mirror of an Outlook. I do not
want to show any custom forms with or without code in reading pane,
strictly messages with plain and HTML body (do not care about messages
with code).
I am a beginner in HTML, but I think that this is possible to achive.
