Mac Outlook 15.11 2015 "connection to the server failed or was dropped" (Error # -3253)

In Outlook 15.11 2015 on Mavericks, I am constantly getting a "connection to the server failed or was dropped (Error # -3253)" for my pop accounts when I send/receive. I can send mail, but not receive it. I use GoDaddy as a hosting service. I have tried deleting the account, as well as the profile under profile manager. Has anyone else encountered this issue? If so, do you have a solution? I see on the MS forums where this is an issue, but I don't see a resolution.

I had this problem, too, and about the same time Safari started acting up by not loading pages. I found that the problem was the Avast Anti-Virus Software that I had installed on my machine. Once it was removed, the problem was solved: no more Safari issues and no more Outlook issues, specifically Error -3253.
