Would like to return back to xfinity email from Yahoo email

@user_p4d99w 

I don't really like yahoo appearance and would like to switch back xfinity email. How I can do that?

Unfortunately, once you've moved to Yahoo! Mail there is no going back to Xfinity.  You can always ditch your @comcast.net email address and move to another service.

If you want to keep using your @comcast.net email, use a third party email app like @XfinityThomasB mentioned.  While you can use Outlook, I recommend using Thunderbird.  There are no ads!  If you happen to use Firefox as your browser, Thunderbird is created by the same company, Mozilla.
