Yesterday I changed my Verizon .com password, now I can't access my web mail through Verizon Yahoo. In addition, I can no longer access my mail through my Verizon Yahoo app on my mobile device.
Any advice?
you might have to contact verizon to get your account re synced with yahoo....

yahoo may have kicked you off or something just to make sure your account is safe
