Unable to send email through MS Outlook

As of just this morning, I am unable to send email using MS Outlook.  Can receive email ok, just not sent.  Seems Outlook is unable to connect to outgoing mail server.  All settings are the same as previous (all day yesterday and earlier this morning) when able to send and receive.  Spoke with Jacob at Cox CS and he advised nothing has been updated on the mail servers.

Can anyone advise if having a similar issue?  Any trouble shooting advice welcome.  Thanks.

    Additional info...

    Have completed restart, reboot, recreate mail box accounts and all other basic tasks to attempt to resolve, no joy.  No error received when sending, sending task just hangs with status listed as "executing" forever.  Will never move to receive unless I delete the message I am attempting to send, and once outbox is cleared, then it will successfully receive messages.

  • Are you able to send and receive email if you login to the Cox website and use Web Mail?

    Hi Michael, thanks for your reply. Yes, I am able to log into cox webmail using my browser, and then yes, able to send and receive emails through the browser, just not able to send using my email client, Outlook.

    Also of note, it seems the port I am using for outgoing mail is now blocked? I attempt to telnet the port and it comes back as cannot open connection on port. Did cox change something?
  • Is this happening on more than one device connected to your home network? Are you experiencing this issue if you are outside the home?

    Here's a list of tasks completed to this point in order to resolve not being able to send Cox email from Outlook email client, all to no joy:

    •Restart Outlook (email client) •Firewall Disabled / Closed •Reboot System •Remove then Create Mail Accounts in Email Client as Previous •Select SSL Option for Outgoing Server •Change Mail Server to IMAP (along with all other required changes to support this change) •Change Port to Secure (465) for Outgoing Server •Change Port to Secure (465) for Outgoing Server with SSL Option Selected •Change Cox Passwords for Accounts then Populate to Mail Accounts in Email Client

    After effecting each change, test emails were sent from a gmail account, emails were received by Outlook, but Outlook could not send email after each change, as connecting to outgoing server with Outlook is unsuccessful. Email can be both received and sent by logging into Cox webmail portal online using an internet browser. My feeling is that this can only be a SMTP server issue on Cox's side - as somehow I can no longer connect to outgoing SMTP server. At this point my only hope (and option at this point) is that this change is temporary and with time the setting will resolve back to accept my connection. In the mean-time, any assistance is appreciated.

    UPDATE  » 

    As was suspected, 24 hours after this issue appeared, it turns out to be a Cox issue that has resolved itself, as I am now able to successfully connect to Cox's SMTP server to send email with my email client - with all mail account settings the same as prior to outage.

    Very frustrating to say the least - NO THANKS TO COX - for the wasted day yesterday. 

    I will appeal to the Cox personnel that post to this forum to inquire about why this outage might have occurred.  All techs or support personnel I spoke with assured me no changes were effected to their SMPT servers, when, at least in my case, most assuredly, something did change.  With all the hardware and software involved, I know chances are slim the cause can ever be pinpointed, but I would appreciate some effort to assess so this does not happen again.

    My advice to those who may run across this thread facing a similar issue, if you can, wait for 24 hrs to see if the issue resolves itself.  Before going through the trouble of rebuilding, reinstalling, restructuring, and otherwise blaming a system that was working fine one day and then all of a sudden is not, wait it out for a day or two to see what happens, if time permits of course.  Good luck.

    Over and out for now - with hopes not to have to post back on this topic ;-)

    This was posted up in the Outlook 2016 continually prompts for username and password... thread on April 21, 2017, explains a great deal that could have caused my issue.  My question would be, why don't all tech support or customer service folks know of this webmail migration so they can advise it is taking place?

    If I had been informed of this yesterday, it would have eliminated much of my frustration in trying on my own to correct something that could not be corrected by me - as the issue was not on my end.  I know Cox is a big company, but they need to have better awareness among tech and support employees of these updates, migrations, etc., that might cause issue with customer facing services.
