If I am typing out the body of an e-mail and press the @ sign, Outlook tries to insert a link to one of my contacts into the body of the e-mail. I really just want to type the @ symbol. I realize that I can just press the ESC key at that point, but I can't think of any reason why I would use this. Is there a way to turn off his feature?

This is Outlook 2016 client.
