Email Send/Receive Error Message

I was just about to update my message to add that I am downloading from the Xfinity servers to Outlook 2021 on my desktop PC.  I just now checked my laptop which utilizes Thunderbird and I received a popup message stating the connection the the comcast.net servers has been changed.

So, it doesn't sound like a 3rd party email issue as two different ones are experiencing an issue.

Webmail works fine.

Also, no issue downloading emails to Android phone S25 Ultra.

Also, I sent a test message using Outlook2021 and I received the Send/Receive error message; however, the test message was in fact sent and received.  So, the issue appears to be downloading to PC and laptop.

Update:  Just received a different message on laptop with Thunderbird state the connection to comcast.net servers is now refused.

@KittyMom Is there any way an email filter could have been created? To check email filters:

1. Sign in to Xfinity Email using your Xfinity ID and password.
2. Click the Gear icon on the top-right of the navigation bar, then click Email Settings.
3. Mail Filter Rules page, you can also choose Edit to modify the filter rules or Disable to turn off the filter. Click the trash icon to delete the filter.
4. Click Save to save your filter.

I also recommend checking the security settings in the Xfinity Email website. This may affect your ability to manage your Xfinity Email (Comcast.net) through third-party programs like Outlook, Google, Apple Mail, Thunderbird, and more. 

Update email security settings

Both of the items you asked about do not appear to be the issue (see below):

I just did another send/receive on my desktop (Outlook 2021) and received the following new message.

I did not click Yes or No until I hear from you.  Thanks.

I am having the same issue.  However, the incoming servers started working for a few minutes, and then stopped working again.  This leads me to believe that this is a Comcast/Xfinity server issue. Hopefully, they will fix it shortly!

@jtatsud thank you for reaching out over Xfinity Forums. Sorry to hear about the email issues, I know how important it is to have access to your communications. I noticed the OP had mentioned they were using a 3rd party client to access their emails.

- Are you also using a 3rd party client? 

- Do you have any issues when accessing your emails here: https://www.xfinity.com/email ? 

Xfinity email is in the process of moving to Yahoo mail, and we have started sending out communications: https://www.xfinity.com/support/articles/yahoo-email-migration-overview

- Have you received a notification, and stared the process of moving the email to Yahoo and accepted their terms of service? 

@edsaurus

How are you accessing your e-mail are you accessing it through third party client? Can you access your email via https://www.xfinity.com/email or by logging onto the email app an go to search option and type email login

Other users are experiencing these problems this morning on both Windows and iMac Outlook clients.

@user_foz4sq - Thanks for leaving a comment and letting us know! Are you still experiencing issues? If so, what troubleshooting have you tried so far? Feel free to create your own new post for further assistance from our Digital Care Team :)

I'm sorry to read that you are having this issue as well jmcnemar1. I know it can create a big communication gap when we are unable to fully access our email. Based on the error and experience it seems like the email settings need to be updated. I know you haven't made any changes recently, but our settings may have been updated causing this interruption. If you visit https://www.xfinity.com/support/articles/update-pop3-110-995 you will find the correct settings depending on the email client you are using. 

What outlook version are you currently using? Can you tell me what the client settings are showing currently? I would love to help out and make sure you can fully access your email again. 

Hello, @MLA21703! Are you still running into difficulty today?

@kewpy have you received an email from Yahoo for your Comcast email yet? 

Thank you for reaching out through our Community Forum user_kv6j9e. If there was an update on our end, it could potentially require your settings be adjusted.  If you visit https://www.xfinity.com/support/articles/update-pop3-110-995 you will find the correct settings needed for your email client. Please let me know if this helps any.

Hey there, @user_lftf1g. Some of the community members have mentioned the issue with the POP3 service has been restored, are you able to confirm from your end? 

Good Afternoon, @T2b420! Thank you so much for taking the time to reach out to us here on the Xfinity Forums. We did notice that a lot of the customers have reported the email concerns have resolved, are you still having troubles? 

Hello, @user_nksoay! I'm sorry to hear that you ran into this issue with your email. Is it still ongoing?

Nope.  They haven't propagated the valid certificate across the board.
