I have 2 verizon email accounts set up in Thunderbird they were both working fine until about 2 or 3 days ago. The bring.... account does not allow me to send email. I first get the message in question box. Then asks for password. I put in my password and it does not work. I have uninstalled Thunderbird and reinstalled it. Still no good. I changed my user ID and password at verizon and updated in Thunderbird still no good. I have now spent many many hours with verizon tech support and on my own trying to fix the problem. Please help.
