Yahoo email is the worst idea ever...

@user_5037un 

What are you doing with this email migration to Yahoo? I have had & been happy with Comcast for 20 years same email and everything. If THE switch to Yahoo mail is mandatory I'll be leaving. There is NO way to integrate with Outlook and NO CUSTOMER SUPPORT. Comcast Please Pay Attention to YOUR CUSTOMERS!

If you're using the new Outlook, you're right, there is no way to integrate your @comcast.net email.  However, some users have reported that if you set up your email in the old Outlook first and then switch to the new Outlook it will work.  Since I don't use Outlook I cannot help you with going through the motions to set this up.  Hopefully someone who has will chime in here to help you out.
