How do I get to comcast email?

I definitely understand how important it is to be able to access your emails @user_a4y4un, and I also know how stressful it can be when you're locked out. Have you already migrated your email account from Comcast to Yahoo? Knowing if your account has officially made the switch yet will help. If you log into the Xfinity site, do you see an on-screen prompt asking you to accept Yahoo's terms?

Tips to ensure a smooth transition

I have critical emails I must get to!  I have tried everything to get to my email ... With Comcast and Yahoo!  This is getting awful!  I have never seen anything to tell me we are moving your email to Yahoo??  I don't want Yahoo mail!  I will use it to get my critical emails out of there!  But, will not keep that email!  I don't care for their site!  

If you have transitioned to Yahoo! Mail there is no going back.  If your comcast.net email is there, you would sign in at either https://mail.yahoo.com or https://login.yahoo.com with your comcast.net credentials.  Otherwise you go to webmail and sign in there.
