Ok...the problem started this morning. I have 4 Yahoo accounts and 3 are working fine except 1. I am not able to receive any emails; however, I can send emails and see all of the folders. I deleted the account and added again still the same problem. I rebooted the phone and still the same problem. Does anyone know how to fix this? When I access that email account it say no email. I am using standard Yahoo mail that comes with Droid Incredible. I am not using Yahoo Mail app. I installed it today and I can access all email accounts but it is sucking up battery at a supersonic speed.
