Non existent support

user_ekk92 - Thank you for your feedback. I understand how frustrating it can be when email isn’t working as expected, and I appreciate you taking the time to reach out. While we aren’t able to troubleshoot Outlook directly since it’s a Microsoft product, we’re absolutely happy to help make sure you can successfully sign in to your Xfinity account and access your comcast.net email through the Xfinity Connect website.

Please keep in mind that using third‑party email clients such as Outlook, Apple Mail, or Thunderbird to access your Comcast.net email can potentially put your Xfinity ID and password at greater risk of fraud or other security issues. For the best protection and experience, we recommend accessing your email directly through Xfinity Connect whenever possible.
If you do choose to use Outlook, we strongly recommend confirming that it’s set up using IMAP rather than POP. IMAP is the preferred configuration for several reasons:

POP can cause issues when you check email on more than one device, since it removes messages from our servers and delivers them only to the device that downloads them.
IMAP keeps your messages and folders on our servers, making it much easier to sync email across multiple devices.
Any changes you make—such as deleting or organizing messages—will automatically appear on all your devices.

You can find additional details about proper IMAP configuration here:
https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email.  
Also, please remember that anytime you change your comcast.net email password, you’ll need to manually update that password in Outlook or any other third‑party email app. These applications don’t update stored passwords automatically, and an outdated password will prevent them from connecting to the mail servers. 
If you’re able to access your comcast.net email successfully by signing in to Xfinity Connect and clicking Email, that indicates the service itself is working correctly. In that case, any remaining issues would be specific to Outlook, and Microsoft would be the best resource for assistance with their product.
We truly appreciate your understanding, and we’re here to help with anything related to your Xfinity account or email access through our platform.
