Common issues
Thunderbird says it cannot find the settings.
On the first screen, click MANUAL CONFIGURATION under the email address, then enter the settings yourself: server mail.officeniaga.com, incoming port 993 and outgoing port 465, both SSL/TLS, and your full email address as the username.
Thunderbird suggests port 587 for outgoing mail.
Port 587 is closed on our server. Change Connection security to SSL/TLS and Port to 465.
