Windows Live Mail by default changes straight quotation marks (" and ') to typographic quotation marks, aka "smart quotes" (“, ”, ‘ and ’).

This often results in the recipient of the email seeing blank rectangles or other symbols instead of the smart quotes, due to encoding problems.

Unlike in most programs, there's doesn't seem to be any built-in option to disable this, and searching online for solutions only leads to workarounds, like hitting Backspace immediately after typing a single or double quote, and switching to "Plain text" mode.

Is there any way to disable this behaviour?
