How do I disable smart quotes, apostrophes in Mac Outlook 2011? In Mac Outlook 2011, when I type a message that contains an apostrophe or a quotation mark, Outlook corrects it to a "smart" apostrophe or a "smart" quotation mark, and I'd rather it didn't. 

Is there any way to disable this feature? So far, I've unchecked all the autocorrect and autoformat preferences, and I've set my composition settings to plain text and my encoding settings to UTF-8 (two suggestions I saw elsewhere). None of those worked. 

What else should I try?
You can turn Smart Quotes off by unchecking "Smart Quotes" under Edit > Substitutions > Smart Quotes
