Hello dnelso21! Thanks for joining our Xfinity Forums community and sharing the trouble you are having with the pop3 server through outlook. I'm very sorry that we are having trouble with receiving email through outlook. I know how vital email is for our daily lives and I would love to help correct the issue. Are you still able to send email through outlook? Are you having any trouble with accessing your email online at connect.xfinity.com? A more common thing I am starting to see as well is our migration to yahoo mail. Have you received a notice or prompt to move your email account to yahoo mail yet?

@XfinityPaula​ Hi Paula - as stated in my post, I am able to send mail via Outlook (to the SMTP server) and I can still access via connect.xfinity.com.  I agree that it may be related to the Yahoo migration but I have not received any notice or prompt to change my account/server settings for that. I'm happy to try if you have the appropriate info.

We have recently been alerted that access to Xfinity Email via 3rd party applications is currently offline. Our engineering team is working on the issue, and we hope it's resolved soon. In the meantime you can access your Xfinity Email directly from the Xfinity Email Web Portal.

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.

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:

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.

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?

Comcast Pop Server is still not working, can access through Xfinity website and can send mail through outlook.  Still can receive mail through outlook.  Comcast/Xfinity please fix your pop server.  Thank You!

Thank you for the information @user_g9jyqu. Have you tried removing the account from outlook and adding it back on, or verified the incoming and outgoing settings on Outlook with the instructions here?

Hello, @Nat_IV Our team can help. We are all live agents. I recently upgraded my phone and had to enter my password for Outlook for IMAP. This solved my issue, and I am receiving all of my emails. IMAP is generally favored over POP by those who check their email on multiple devices since it provides a more consistent experience. Does Thunderbird allow you the option to switch to IMAP? For some email applications, switching from POP to IMAP is as simple as entering your Comcast email address and password.

@XfinityJeff​ Hi Jeff - I'm one of the other users of POP3 for my Comcast.net email that has had issues since 12/8. I prefer to keep using POP3 with my Outlook classic mail program as it maintains a local copy for me to view offline.  That said, I agree with others that it seems as if something changed with the POP3 server(s) that Comcast is using. I get the same "request timed out" error message when trying to receive messages from POP3.comcast.net server.  Sending messages works fine - as does viewing them via the Xfinity email website. So...the question is.. did any of the POP3 server configuration settings change?  Server name (still POP3.Comcast.net)? Port number (still 995), Security protocol settings?? Anything??  Everyone on this thread appears to have made NO changes to their email apps that would have caused this....especially since we all started having the issue around the same date/time.  Let's get beyond the Level 1 responses for inexperienced users and dig down a bit on your side, please.  Kind regards...

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.
