Accessing email via Thunderbird

[#1]

Recently, my password is not recognized in Thunderbird when collecting email even though I can access via webmail using the same username/password combination.  My last email in my Thunderbox email is 9th September so the issue seems to have happened after that. 

My server settings remain:

Server Type: POP Mail Server

Server Name mail.plus.net

Port 110

Connection security None

Authentication method Password, transmitted insecurely

Can anyone suggest what's needed to fix this please?

Are you on or off network?

These are the preferred settings for plusnet email.

IMAP: imap.plus.net port: 993 TLS/SSL

POP3: mail.plus.net port: 995 TLS/SSL

SMTP: relay.plus.net port: 587 STARTTLS

Password authentication would be set to "Normal password"

When you get the prompt "Password not recognised" try logging on with username@username.plus.com if you are with plus.com and use the same password.  I had the same problem using Outlook and that sorted it.

Ignore trying to fiddle with the email application settings.  There are a multitude of reasons that one cannot connect to email servers but unfortunately in most email clients ALL connection issues report as a 'password' error.

Running the email server connection diagnostics (link below) is more likely to give a clear indication of what the problem is.

Thank you for the support given. I managed to fix it by fiddling with the username and reentering the password. I referred to https://www.plus.net/help/archive/email/thunderbird-setup/

Unfortunately I'm not 100% how I fixed it but it seems to work now!  Thanks again!
