Live customer support phone number for email troubleshooting

I've used Thunderbird for all of my emails for many years and have had no problem connecting to my main comcast email until just recently. Suddenly, Thunderbird can no longer connect to our comcast email account to download new emails or send new emails (it's weird, but it will connect every once in a while and download new emails successfully, but this happens very rarely--maybe it's successful only once throughout the day.)  I also use the Bluemail app for all my email on my android phone and it suddenly stopped connecting to my comcast email at the same time. I've verified that my comcast password is correct and all port settings.

@user_f4f3a2 if you are having difficulty sending and receiving email from a third-party email program like Thunderbird, Outlook, Apple Mail, Gmail or others you may need to reset their Xfinity ID password at Xfinity.com/password. After resetting their Xfinity ID password, they will also need to ensure the password stored in the third-party email program is updated to the new Xfinity ID password to continue sending and receiving emails. 
 

I did this and it still doesn't connect.

@user_f4f3a2 Xfinity now requires the use of secure ports: for incoming mail, switch from Port 110 to Port 995 with SSL; for outgoing mail, use Port 465 or 587 with TLS or SSL. If these settings are not updated, you may still receive emails but will be unable to send them. Ensure your email application is configured correctly to avoid disruptions in service.
