Don’t open Word attachments in Reading Layout

When I receive a .doc or .docx attachment in Outlook and double click on it, Word opens it in Reading Layout (two pages side by side) instead of normal mode.

Opening a document outside of Outlook opens it normally inside Word.

Is this a Word issue or a Outlook issue, and how do I fix it?

Word - Read Mode - buttonThat is a Word option. Outlook doesn't control how attachments are being opened.

To change this behavior and always open the message in the Print Layout;

Word 2003
Open Word-> Tools-> Options-> tab General-> Allow starting in Reading Layout

Word 2007
Open Word-> Office Logo-> Word Options...-> section Popular-> Open e-mail attachments in Full Screen Reading view

Word 2010
Open Word-> File-> Options-> section General-> Open e-mail attachments in Full Screen Reading view

Word 2013
Open Word-> File-> Options-> section General-> Open e-mail attachments and other uneditable files in reading view
