POP3 Server Not working

I am having the exact same issue (started Dec 8) with Outlook trying to receive email via POP3 server

Having the same issues as of this morning.

Trust me here.  I have wasted MANY hours on this thinking I had [Edited: "Language"] up my Thunderbird client 

It has become abundantly clear to me that the fault lies 100% with Comcast pop3 servers. 

I SUSPECT it has to do with their changeover to Yahoo.

I could get relief from time to time by using a VPN and trying to retrieve emails with Thunderbird from other towns.  It actually worked now and then.

I HOPE I'm good now without having to "move" to a different town.

This is a pathetic situation and I feel really sorry for folks who need their Comcast pop3server to work.

Hopefully things will return to normal soon.

Comcast is horrible.

I will report my Thunderbird pop3 settings that are working at the moment in a few minutes.

Take it all back.

Accidentally closed Thunderbird.

Back to VPN land

I am having the same issue, seems a DNS issue did the IP address change on xfinity side for pop3.comcast.net?

Well, I surrender.  It asked for my password (not sure why) and the new messages magically appeared 

Here are my settings, for what they are worth.

Your results may vary.

I am going to try to install Thunderbird on another computer to see if the defaults recommended by Thunderbird are the same as my settings.

Server Type: POP Mail Server

Server Name: pop3comcast.net  Port 995

UserName:

xxxxxx@comcast.net

Connection security:

SSL/TLS

Authentication method:

Normal password

Outgoing Server Settings

Description:

Comcast

Seerver Type:

SMTP Outgoing Server

Server Name:

smtp.comcast net  Port 465

User name:

xxxxxx@comcast.net

Authentication method:

Normal password

Connection Security:

SSL/TLS

Fresh install on another computer now downloading 12,168 files.

Only difference from my Server Settings is this Thunderbird default.....

Server Name:

mail.comcast.net

AND outgoing server

Authentication method:

OAuth2

Can't decide if I should change my settings.....

If it ain't broke.......

One last suggestion.

After I changed to the default, I had to turn off my computer, reboot, and then open Thunderbird.

It then required a password, and I think the default settings will (hopefully) work.

Can't explain how or why that worked.

Having the same issue, what is going on Comcast?

Right now, everything (POP3 with Thunderbird) and (IMAP with my Android phone) is working fine for me.  At this moment that is.  That is constantly subject to change.  Both types of server seem to go out of service at the same time for me.
I highly doubt that there is anybody to blame here EXCEPT COMCAST.  I don't understand why more people aren't on this forum complaining.  

Good morning @user_g9jyqu, and thanks for posting to the Xfinity forums, I hope this message finds you well. As someone that uses email for both work and personal use, I can understand how frustrating it can be to lose access, but you have come to the right place for help. How do you access your email? Is it through the Xfinity website, or a third party app such as Outlook?

My apologies ‼️‼️

Glad to know you're a human 😊 

I prefer POP, and my outages occur concurrently with pop3 on my computer and imap on my phone.

This failure is all on Comcast.  Sometimes works, sometimes doesn't.

Has to do with the server (be it POP of IMAP) not "answering calls."

Bouncing around on VPNs will let me find one that works.

System wide failure related to moving to Yahoo is involved I bet.
