Setup Mozilla Thunderbird

First remove the email account via the instructions below.

Follow install instructions below with two very important changes:

  • Choose Manual Config, regardless of whether your service provider is listed or not. You will need to manually enter in your IMAP and SMTP settings.
  • Use the following for Incoming IMAP:
    • Server Hostname:
    • Port: 993
    • SSL: SSL/TLS
    • Authentication: Normal password

All other settings remain the same as before, including your SMTP (outgoing server) settings.
