Outgoing Email Issue on 3rd party apps

@user_eoco6h​ 

I have the same problem, I have been dealing with it for over 1 month.

Sending messages works correctly when accessing my email in the browser at https://connect.xfinity.com/appsuite

When using any third party email apps on the desktop PC or smartphone, messages fail to send with either an "SMTP Server Connection Timed Out", or a "Invalid username/password for SMTP Server" error message.

I have tried various outgoing server settings. Currently I have it set to:
Outgoing Server - smtp.comcast.net
Port - 587 (have also tried 465)
Security - SSL/TLS

Xfinity please assist.

What email client are you using?

IOS Mail on iPhone 13.  I also tried Elgin and Outlook.  

@user_ks1e8 Thank you! Can you please check your "Outgoing" mail server, and see if it's set up correctly?

It is and has been.  I have been through all of those settings with Comcast Email Support and still no resolution.

Thank you for your feedback, user_ks1e8. I believe the reason that you have had so many issues when attempting to contact us regarding your email, is that we cannot troubleshoot Outlook, IOS mail or other 3rd party apps as that is not our product. Please remember that using third-party email clients (e.g., Outlook, Apple Mail, Thunderbird, etc.) to access your Comcast.net email address can potentially expose your Xfinity ID and password to fraud and other risks. We recommend you access your Comcast email by going to Xfinity Connect. 

We also recommend ensuring your Outlook configuration is set to IMAP vs. POP. We recommend only using IMAP configuration for your comcast.net email for the following reasons:

- POP can cause problems when checking your mail from more than one phone or computer because POP removes the mail from our server and delivers it to your device.
- IMAP makes it easier to sync your email on multiple devices because your folders and mail remain on our server until you move or delete them with your device.
- With IMAP, the email changes you make on one device, like your smartphone, are reflected on your other devices, like your laptop.

Additional information about IMAP configuration can be found here. 

As a reminder; any time you change your comcast.net email password you will need to make sure you update Outlook or any other email client with the new password there. The passwords stored in those third-party email clients are not updated automatically and will not allow you to connect to the email servers without inputting the new email password there.

Unfortunately, if you are not having difficulting accessing your comcast.net email by going to Xfinity Connect, then the issue is not related to Comcast and you must contact Microsoft directly for help with their Outlook product and getting your passwords updated there. 

Please let us know if you have any other questions related to your Xfinity services.
