Email Application Login To POP3 Mailbox Failure
Enthusiast - Level 2

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 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.
