You can go to Tools > Options > General and uncheck "Allow starting in
Reading Layout".
Typically, documents opened by double-clicking a Word attachment to an email
want to open in Reading Layout. The best advice is: NEVER open a Word
attachment that way unless ALL you want to do is read it. The problem is
that a document opened that way is stored in a temporary folder. If you edit
the document and save, the changes affect only the file in the temp folder.
As soon as you close the document, the temp folder goes away and all your
changes are lost. Instead, SAVE the attachment to a permanent folder, then
open it there to do the editing.
