    I finally found the solution.  It wasn't a Cox problem, nor was it an e-mail client problem.  Turned out to be a 3rd party software issue.

    On the Apple discussions forum, it was suggested to download the EtreCheck diagnostic app for Mac; it paid off. The problem turned out to be the following “Unsigned” file: com.DataFormatSearchP.plist.  I have no idea what an “Unsigned” file is, or what this one did, but deleting it fixed my problem. Mac Mail is finally working!

    Thanks for everyone's replies.

I've had the exact same issue since Wednesday 10/9.  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.

Hi JTKH,

Since you're on a Mac, check to see if you can send and receive e-mails using Mac Mail.  If both Outlook and Mac Mail aren't working, you're probably facing the same dilemma that I'm in: there's a problem with the Cox servers causing my account to possibly being blocked.  It's been 10 days for me, and still no word from Cox, and still no resolution to this problem.  I'm very frustrated!

    Hi Bayman, this case is still being escalated and worked on, and we apologize for the delay. Typically, if there is no issue at all with the Webmail, and you are able to send and receive emails on our website, we refer the customer to the manufacturer of the Client server. For additional support, please reach out to us at cox.help@cox.com, Facebook, or Twitter. -Kevin M. Cox Support Forum Moderator
