Spent over an hour on cox tech support and to no avail, still can't send/receive email on Outlook (2011) on my mac desktop. Lots of basic questions suspecting my need, which it's not. Wanted to sell me tech support contract. Going nuts. "Outlook can't find the server. Verify the server information is entered correctly in the Account Setting, and that your DNS settings in the Network pane of System Preferences are correct." I have not changed anything in this regard for years! Please advise and help.
