I just reinstalled Outlook 2011 (14.3.6) on my 10.8 Apple system, and I see a weird behavior: if I type the word

I'll

   it autocorrects it to

I'Ll

    weirdly capitalizing the first letter after the apostrophe. I went to the Autocorrect Preference panel and tried to enter it into the Exceptions lists, but they don't seem to take - I try to add it to the First Letter tab, and it never gets put on the list.

I did notice that the problem went away when I uncheck "capitalize 1st letter of sentences". Why does it think that an apostrophe marks the fist letter of a sentence??
