Added email accounts Roadrunner 1 and Yahoo account
Attempted to add Roadrunner , was able to install and sync
Received emails ok but could not send
Got error message "unable to sign in" after send appeared to have worked.
Fumbled around, uninstalling the Patch for better web surfing, no difference; turned unit off removed battery; deleted reinstalled the email addresses; still no help ...
Then, per the suggestion above ...
2nd Roadrunner account outbound email address password changed to bogus value, resync'd, changed the password back to the correct value, resync'd and sent mutliple emails successfully!
