Outlook capitalized the next letter after an apostrophe EVERY time.

I'm having an issue where EVERY time I use an apostrophe in Outlook for Mac (e.g., "I'm," "I'll,"), but letter immediately following the apostrophe gets capitalized (e.g., "I'll" --> "I'Ll") as some sort of autocorrect malfunction (I assume).  In addition, I'm no longer able to type - I'm not sure where the cursor moves (or what menu is being activated), but I just get an error "boop" sound every time I try to continue typing.  The only solution I've found is to click where I want my next word to be, type that word, then go back and correct the automatically capitalized letter.  Obviously, that's less than ideal.

Has anyone else had this problem?  Does anyone know of a solution?

Thanks!
