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?
