"Unable to establish TLS connection to POP3 server. The server may be down or may be incorrectly configured. Please verify the correct configuration in the Server Settings for your mail server in the Account Settings window and try again."

From the menu bar select Tools-Account Settings-Server Settings for Inbound server.

Tools-Account Settings-Outgoing Server (SMTP) for outbound server.

No menu bar showing with Tools? Press the alt key.

In the left pane of TB, left click one time on the name of the account (e.g.xxxxxx@gmail.com). Near the middle of the page which is displayed, click 'View settings for this account'. Click on the second line 'Server Settings'. You may also need to verify the 'Outgoing Server (SMTP)' settings. Check with your Internet Service Provider if you have questions about the correct values.
