Outgoing Email Problems

So here is my experience.  Kind of long but may be helpful.  I use a Samsung android smart phone with the standard email client and a old Windows XP computer using Outlook Express (I know its ancient, but it still works!)  As of Monday Feb 26th 2018 everything worked fine, meaning I could receive and send email from the phone and PC without issue.  Tuesday morning, Feb 27 2018 I had no issue receiving emails but noticed I could not send from the PC.  Tried the smart phone and still could not send.

I got on Cox support site, read the info and checked all the server names, port #'s, etc on my phone and PC.  Everything correct but still could not send.  I then remembered receiving a email from Cox about them upgrading email service and re-read it.  At the bottom they said you "MAY" need to reset (e.g. change) your password to make it work.  So Wednesday afternoon I logged into my account, changed my password, waited about 15 minutes, then got into the email client on my smart phone and Outlook express and changed the passwords.

Everything worked!  I could send and receive emails.  It worked fine on both the phone and PC from about mid day until I went to bed at 10 PM.  I rand multiple tests between @cox.net and my outlook.com email account.

Then I got up Thursday morning and I could not send emails again.  Very frustrating!

I then chatted with COX, they gave me a Tier 2 phone number, I called them and didn't get a solution but they told me a lot of work was going on with the outgoing server.  Note: I did explain precisely what happened to me.

Anyway, although frustrated I do have my outlook.com email account and Cox web mail does work.  So I can get by for a while.

Hope this helps.  I plan to keep testing over the next week or so to see what happens.
