[NFBCS] Comcast Email Users Beware!!!!!

[Bradford Snyder]

Setting up Comcast email with Yahoo on Microsoft's Outlook, requires either doing so with Open Authentication (OAuth), or creation of a Secure Mail Key.


To add your Comcast.net email account to Outlook, use the steps below:



Option 1: Set up your account without IMAP (OAuth)

Open Outlook.
Click Add Account.
Enter your full Comcast.net email address in the field provided (make sure to include the @comcast.net part) and then click Continue.
Enter your Comcast.net password in the field provided and then click Select provider.
Choose Yahoo from the list of mail providers.
Click Continue.
Enter your Comcast.net email account password again and then click Next.
Click Agree to allow Outlook to access your Comcast.net email account and to add functions like your Yahoo contacts and calendar.
- You'll see a success message when your emails are synced to Outlook.
Click Done.


Option 2: Set up your account using IMAP

(requires creation of a Secure Mail Key). 

Open Outlook.
Click Add Account.
Enter your full Comcast.net email address in the field provided (make sure to include the @comcast.net part) and then click Continue.
Leave the password field empty for now and instead slide the "Show more" toggle button to the right.
A list of settings will open. Use these IMAP and SMTP settings:
IMAP incoming server: imap.mail.yahoo.com
Port: 993
Secure connection type: SSL/TLS
SMTP username: Your full @comcast.net email address
SMTP outgoing server: smtp.mail.yahoo.com
Port: 587
Secure connection type: SSL/TLS


Next, you'll need to generate an app password:

Sign in to your Yahoo Account Security <https://login.yahoo.com/account/security?.lang=en-US&.intl=us&.src=yhelp> page.
Under "External connections," click the App passwords tab.
Click Create app password (find this on the right side of the screen, next to the External connections box).
Enter your app's name in the text field.
Click Generate password.
Copy the app password.
Return to Outlook and complete your IMAP setup:

Paste or enter the app password you just created into the password field.
Click Continue.
Click Continue again to sync your IMAP account to Outlook.
- You'll see a success message when your emails are synced to Outlook.
Click Done.
HTH.

Greetings everyone:
 
If your email address is not something at comcast.net <mailto:something at comcast.net>, feel free to disregard this email. However, if your email is being handled by Comcast and (more importantly) you use Microsoft Outlook to send and receive your Comcast email, then please pay heed to this email.
 
 
Background
 
Starting in June, 2025, customers with a Comcast email address were being “invited” to “upgrade their email account to Yahoo Mail for a better email experience at no extra cost.” (Parenthetically speaking, what this represents is a not-so-well-hidden attempt by Comcast to reduce the number of customers for whom it needs to handle email)
 
According to the Xfinity page https://www.xfinity.com/support/articles/yahoo-email-migration-overview,
 
“Your comcast.net <http://comcast.net/> email address stays the same — and so do your messages, folders, and contacts.”
 
According to information from https://www.xfinity.com/support/articles/yahoo-email-migration-overview,
 
“this is an upgrade we are offering customers at no cost so they can access their email on a better platform with enhanced security, more features, and a mobile app for easy access on the go.”
 
 
The Problem
 
I have been working with individuals whose Comcast emails were (with their permission) transferred to Yahoo. While their emails are reasonably accessible using Yahoo’s webmail interface, and while comcast.net <http://comcast.net/> emails handled by Yahoo are retrievable using the native iPhone Mail program, it has been virtually impossible to connect Microsoft Outlook to comcast.net <http://comcast.net/> emails that are processed by Yahoo email servers. I am working with the folks at Microsoft and Yahoo in an attempt to resolve this issue, but so far, I have not had any luck solving this problem.
 
 
The Bottom Line
 
If you rely on Outlook to send and receive comcast.net <http://comcast.net/> emails, do not accept Comcast’s “invitation” to have your emails transferred (they say “upgraded”) to Yahoo!
 
Yours sincerely,
 
Curtis Chong
