Please send a screenshot of the error message. Are you getting a problem retrieving or sending email - or both?

Can't get a screen shot.

error is

Login to account " xxx@YYY" failed.

Login to server mail.###.com withj username xxx@YYY failed.

Before you do anything make sure your Firewall is allowing Thunderbird access to internet.

Exit Thunderbird Access Firewall - this might be the default that came with computer or it might be controlled by the Anti-Virus you installed. Thunderbird must be set up as an allowed program.

As this is a spectrum server you need to tell us what comes after the '@' in email address in order to know what server settings you should be using. But the following link advises you.

• https://www.spectrum.net/support/internet/spectrum-email-server-settings

Pop incoming

• Port: 995
• Connection Security: SSL/TLS
• Authentication Method: Normal Password
• Username = full email address
• password: same one you use to access webmail account

SMTP:

• Port: 587
• Connection Security: STARTTLS
• Authentication Method: Normal Password
• Username = full email address
• password: same one you use to access webmail account

As you have updated a password then did you update the stored password as follows:

In Thunderbird

• Settings > Privacy & Security
• Scroll down to Passwords section
• Click on 'Saved Passwords'
• Click on 'Show Passwords'

If asked for password: Is the checkbox 'Use Primary Password' already selected ? If you have previously set up a 'Primary Password' then that is password you need to enter - this password has nothing to do with mail accounts. If checkbox 'Use Primary Password' is not selected ? You have not set this up then: When you start up computer, you get asked to enter a User Account or Microsoft account password - that is the password you need to enter.

Then you can see stored passwords.

If they are not updated to new password..

• Right click on the relevant lines and select 'Edit PAssword'
• Completely clear password and then type in correct password.
• Make sure both the 'mailbox://account....and the smtp://account.... lines have correct password.
• Click on 'Close'
• Exit Thunderbird
• Wait a few moments for background processes to update files.
• Start Thunderbird.

finally got spectrum to admit it was due to old email account from TWC. needed to change password in 2 locations.

thanks dap
