Over the last few days, I have noticed that when I use and apostrophe, while writing an email, in Outlook...the apostrophe is substituted with an ampersand (&) additional letters and signs!  I thought perhaps it was because I was using my cell to respond to emails, but it is also occurring with emails I create using my desktop.   My friend, who uses Yahoo, is having the same issue!  Any idea what is happening and how to fix??  Thanks
