I have been using Thunderbird (currently version 45.4.0) as my email application for many years. Yesterday the program was unable to login to my pop3 mailbox after a passwrod reset was required by my Verizon account. I have entered the new password in the program but it still returns the following notification each time I try to retrieve my mail:
"Sending of username did not succeed. Mail server pop.verizon.net responded: [AUTH] Authentication failed"
I can access the verizon webmail without any trouble.
Please confirm whether there have been any changes to the settings required to access the pop3 mailbox from a 3rd party application.
