Contractions in Outlook 2011

I tend to mis-type contractions with a semicolon instead of an apostrophe. While I'm able to enter the mis-typed contractions in the autocorrect list in Word, I am not able to that in Outlook and it's driving me crazy (I know - I should just work on typing the words correctly...). When I attempt to enter the word "weren;t", for example, Outlook shortens it to "weren." Same goes for any semicolon contraction I attempt to add to the Replace column in Outlook. Is there a workaround?

Thanks in advance for any guidance (that doesn't include re-learning how to type!).
