When I receive a .doc 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 normally inside Word. Is this a Word issue or a Outlook issue, and how do I fix it?
That 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;
Open Word-> Tools-> Options-> tab General-> Allow starting in Reading Layout
Open Word-> Office Logo-> Word Options…-> section Popular-> Open e-mail attachments in Full Screen Reading view
