Thank you for your response. I do not have the ability to configure the connections settings on Mobile Email application and Yahoo does not support IMAP only POP. I have a ticket in with Yahoo to see if they can resolve the issue as Verizon said Its a Yahoo issue. I guess I'm the only one experiencing this issue with Yahoo on Mobile Email with an LG Dare... I have since been able to validate my account , but still get communication errors when i try to read my mail 90% of the time.
