Got letter saying my email account will be terminated on 7/10 unless I agree to Terms of Service policy. Tried to do it but couldnt get in.

No response.  please contact me.

Thank you, @user_humcfa, for connecting with us about your email concerns. We're happy to help. Beginning June 2025, comcast.net email accounts will begin transitioning to Yahoo Mail. This transition will happen in phases through 2026. There is nothing you need to do until we let you know that it’s time to complete the move.

You’ll keep the features you love most about Xfinity Mail when you make the move — including your current comcast.net email address, messages, folders, and contacts.

Note: Moving to Yahoo Mail will only impact your comcast.net email address. None of your other Comcast services will be impacted.

What to expect

You'll be notified 30 days in advance to move your comcast.net email account(s) to Yahoo Mail. When the time comes, you will have three options:

Move your email to Yahoo Mail by accepting Yahoo’s Terms of Service and Privacy Policy to keep your comcast.net email address.
Export your email data using the Xfinity Email Export Portal.
Close your account using the Xfinity Email Export Portal, which will result in email account closure and data deletion.
To learn more about these changes, please visit: https://www.xfinity.com/email.

help-cant log in to the Sait system to confirm my agreement with the Comcast  Terms of Service and Privacy Policy.  what do I do?

Are you familiar with the Sait system?  Does it have something to do with your school?  To me it sounds as though it's a phishing email.  Did it want you to click on a link? 

@user_humcfa Have you been able to follow the instructions my colleague shared? Have you been notified to move your comcast.net email account(s) to Yahoo Mail?

Hello user_bfa3f9! Did the email notification you received also contain any direct link options for you to be redirected to directly from the email?
