oulook email not working on computers

Hello,

My 2010 outlook that is downloaded on my computer is not working . I have not gotten emails on it since the upgrade happened. my mobile and the web (comcast business) site email is.  I am guessing it is not pointing to the correct server. how do I get it to work?

Thank you

here is a link to an official support document containing server settings

maybe make sure your mail client has these same settings. also, you mentioned you haven't gotten email "since the upgrade happened." What upgrade are you referring to, exactly?
