Hi Leatherlady, logging into Cox Webmail (myemail.cox.net) and sending a test message to yourself will tell us if the issue is on the Cox side or within your Outlook profile settings. To check Outlook settings, open Outlook and click on File, then Account Settings. (In older versions of Outlook, click on Tools and then Account Settings.) From the Account Settings window, select your Cox Email account, then click Change. On the Change Account window, ensure your incoming and outgoing server names are correct based on the POP or IMAP settings found at
www.cox.com/.../cox-email-server-settings.html. Under Logon Information, enter your username and password, and then click More Settings. From the Internet Email Settings window, click the Outgoing Server tab. Make sure there's a check in the "My outgoing server (SMTP) requires authentication" box and the “Use the same settings as my incoming mail server” box is selected. Click on the Advanced tab and the Incoming server and Outgoing server port numbers per the “Cox Email Server Settings” article. In the “Use the following type of encrypted connection” drop-down boxes by the Incoming and Outgoing port fields, select SSL/TLS. Click OK. From the “Change Account” window, click Next or Finish. Click on your Outbox and delete any emails stuck in the Outbox. Close Outlook completely. Reopen Outlook and compose a new message to your email address. Type “test” in the Subject line and “This is a test.” In the body of the email, and then click send. Do you get an error? Does the message arrive in your Webmail and Outlook Inboxes? -Becky, Cox Support Forums Moderator
