Go to http://www.mozilla.com/thunderbird/ and download the latest version of Thunderbird (there should be a link to it on the front page). After clicking on the download link, click "Save".

Save the setup program someplace where you can easily find it, like your desktop.

Open the setup program, which should be named something like "Thunderbird Setup 1.5.exe." If a warning dialog appears, click "run". The Thunderbird Setup welcome screen should appear. Click "Next" to begin installing Thunderbird.

Work your way through the setup program, choosing whatever options you prefer or accepting the defaults. After making any changes, click "Next" to continue to the next part of the install program.

When the setup program reports that Thunderbird is installed successfully, click "Finish" to close Thunderbird Setup.

The "Mozilla Thunderbird" icon should now appear on your desktop. Click on it to start using Thunderbird.

The first time you run Thunderbird, you will be asked if you want to import mail settings from another email program. If you've already configured your email in one of the programs listed, select it from the list. Thunderbird will handle the rest and you're done! The rest of the tutorial steps assume you don't have your mail settings already configured in one of the listed programs and want to configure your account settings from scratch. In that case, select "Don't import anything" and click "Next".

If you are setting up a new account, you will be asked what kind of account to create. Select "Email account" and hit "Next".

Enter your name and email address as directed by Thunderbird, then click the "Next" button.

Select "IMAP" as the type of incoming server (Or, if you want to use the POP protocol, select "POP"). Type sslmail.et.byu.edu in the box labeled "Incoming Server" and sslmail.et.byu.edu in the box labeled "Outgoing Server." You should now see the following: Click "Next" to continue.

Enter your CAEDM email name in the box labeled "Incoming Mail Username" and your CAEDM username in the box labeled "Outgoing Mail Username." Then click "Next".

You should now be prompted to enter a name for this account. Call it whatever you want and click "Next". Take a look at the summary, then hit the "Finish" button.

When prompted, provide your CAEDM email name and password.

From the "Tools" menu, select "Account Settings...".

Choose "Server Settings" from the left sidebar. Under "Use Secure Connection," select the button labeled "SSL." The port should be set to 993.

Choose "Outgoing Server (SMTP)" from the left sidebar, then hit the "Edit..." button.

Under "Use Secure Connection," select the button labeled "SSL." The port should be set to 465.

Note: If you have Symantec Antivirus installed, it may conflict with the encrypted connection that SSL provides. Refer to "Configuring Symantec Antivirus to Work With Email" for further details and a solution.

You should now see something like this:

Click "OK", then "OK" again. Everything should now be ready to go!
