[Plugin: WP-Mail-SMTP] Mail won't send/recieve

I can’t get mail to send/receive after changing hosting services about a week ago. Web hosting was moved to godaddy. Our email is not through godaddy, but is hosted on an exchange server.

I have all of the information plugged in to the plugin correctly according to my IT admin, but keep getting a ‘111 cannot connect to server’ error.

I tried setting the form up to work with gmail, but didn’t have luck there either. I got the same error.

Is there a setting that needs to be changed somewhere?
