Cannot send email... (0x800CCC0F) Connection to server interrupted - Comcast customer
This problem has been reported many times by folks who were once Comcast customers but no longer are.
THIS IS NOT ME - I AM A COMCAST CUSTOMER using Outlook 2019 with POP3 under Windows 10, all current on updates.
I use the Mozillia VPN, Windows firewall and Malwarebytes.
I have been a long-time user of this configuration without this problem until recently.
I shut down Outlook every evening and relaunch it in the morning.
Last night I successfully sent an email at 12:15 AM but this morning when launched Outlook it was blocked.
It can only be cured by rebooting.
More generally it happens after a period of time and can be cured by a reboot.
I did retry closing Outlook and restarting it in the safe mode - Outlook could not launch and reported this error:
"The connection to the outgoing (SMTP) server was dropped. Please check the outgoing (SMTP) server settings and try again."
From reading the dialogs of the non-Comcast customers it sounds like there is some sort of authentication discrepancy between Comcast and my OS - any ideas what it is and how to fix it?

Have you tried shutting off your VPN?

@tom94022 Thanks for reporting an issue with outlook. Have you checked and confirmed your settings are all correct? https://www.xfinity.com/support/articles/configure-outlook-express-xfinity-internet?view=app I have a link that has our current settings for email. Take a quick peek and ensure all the settings are correct including the SMTP.
Are you able to log into the Xfinity email account without an issues?

I had two emails stuck, so I exited Outlook, turned the VPN OFF and then ON, restarted Outlook and the two emails were sent.
Pretty clear this a Comcast issue with my Mozilla VPN.
It was not current, so I updated to Mozilla VPN 2.20 which purportedly has minor bug fixes, UI adjustments and other performance improvements.
Not sure if this update fixes my problem so I will leave it open but the work around seems to be exit Outlook, turn the VPN off and on and restart Outlook, a bit of a pain but I don't send too many emails so I can live with it for a while. :-)

Upgraded to lastest version of Mozilla VPN, same problem - emails stuck in Outlook, turned VPN off and Outlook sent emails.
Pretty clear the problem is Comcast rejecting the IP address assigned by Mozilla.
I did install Mozilla on my laptop where I use Infinity to manage my emails; rarely send from there so it is a bit early to see if some intereaction between Outlook and Mozilla is part of the problem.
Not sure exactly what to do at this point other than watch for stuck mails on my laptop; a Comcast solution would be welcome.
