Step by Step Instructions

Step 1 - How to get to the settings

First time launching Thunderbird

When you open Thunderbird for the first time it will automatically start the process of creating an account.

Adding a second account using Thunderbird

If you've used Thunderbird before you need to click on "Local Folders" on the left of the window to get the "Accounts" pane to show. Under "Create a new account" click on "Email".

Step 2 Add a Mail Account

Click "Skip this and use my existing email" on the bottom left.

Enter your name, email address, and password. If you are on a computer that only you use then check "Remember password."

After a little while you should see this. It is incorrect. Click "Manual Config" to fix it.

Use IMAP unless you have a good reason to use POP3.


Change the incoming and outgoing servers to Click the "Re-test" button and it should set SSL to "STARTTLS" for both incoming and outgoing, the ports to "143" and "587", and "Authentication" to "Normal password". If clicking "Re-test" did not set it to those settings, set them manually. Click "Done" when verified.


Instructions are identical to IMAP except the POP3 port needs to be 110.

Step 3 Verify Certificate

If you see this dialog c Click "Confirm Security Exception" (in the future this step will go away).

Step 4 Test message

Send a test email to yourself. As soon as you click "Send" you might get another dialog as the previous step, but it will look slightly different (the location will have a 587 instead of a 143 or 110). Click "Confirm Security Exception" (in the future this step will go away).

You are done. You should get the test message in your Inbox.
