This article assumes that this is your first time setting up Thunderbird.

Note: If you have already set up Thunderbird with another account or made an attempt, you should do the following to get started: From the main panel, right click Local Folders > Settings > Account Actions > Add Mail Account.


Setup Email

1. If this is the first time you have set up Thunderbird, then the following panel options appear as documented in this article.

It is up to you if you want Thunderbird to scan any other email programs and automatically pull in messages from those accounts that are set up. If you are not sure, select Skip Integration.

2. The option appears to create a new email address. Click the Skip this and use my existing email button.

3. Reference the table below to enter the requested information: Your name, Email address, and Password, then select Continue.
Settings Required Information
Your name Enter the name you would like to be displayed in the from field when someone receives your email
Email address Enter your full email address.
Password Enter the password that you set when you created the mailbox in your account manager.

Note: It is recommended that you also select Remember Password unless multiple users have access to your profile on your computer.

4. Select IMAP or POP3 and then click the Manual config button to expand the configuration options.

5. Reference the table below to enter the requested information. Click the Done button when you have finished.

Note: Thunderbird will attempt to find the server settings for you. In many cases it will pull in the correct Server hostnames, but please verify they are correct by referencing the table below. Be sure to verify the Port, SSL, and Authentication settings as well.

Settings Required Information
Incoming Serverhostname mail.<>
Outgoing Server hostname


For customers:

6. A warning message may appear about not using encryption. Although, there are options to set up your connection with SSL, you may still get warnings about invalid SSLs due to the fact that the domain name is a custom domain name.

Select I understand the risks, then click the Done button to complete your setup.

Your email account is now set up. You may begin using Thunderbird.
