Configuring Mozilla Thunderbird on a PC

Step 1: New Account Setup
When you first launch Mozilla Thunderbird, you will see this window. You will want to set up an email account for this tutorial. Select it and click Next to continue.

Step 2: Identity
Fill in the appropriate information
Your Name: This is the name displayed to people who you send email to.
Email Address: This is your email address at UCSD.
Click Next to go on.

Step 3: Server Information
Choose POP or IMAP
When you use POP, all of your email messages from the UCSD server are moved to your computer. Once these messages have been moved to your computer, they are no longer accessible through ACS WebMail. It is best to use POP only when you use your mail client to check your email on one computer.
Selecting IMAP has the advantage of keeping all of your emails on the UCSD mail server, while keeping an updated copy on your computer. This means that you can check your email wherever you are, using a mail client or through ACS WebMail, and your all of your messages will be displayed.
For this example, we will use IMAP.
Incoming Mail Server: Your mail server may be one, or close to the following: popmail.ucsd.edu, ieng9.ucsd.edu, sdcc17.ucsd.edu, etc. If you do not know your mail server, you can check by using the Account Lookup Tool and look for which email your server is on.
Outgoing Mail Server: Type in smtp.ucsd.edu

Step 4: User Names
Incoming User Name: For this tutorial, use your UCSD user name.
Outgoing User Name: Enter in the same thing and use your UCSD user name.
Click Next to go on.

Step 5: Account Name
Account Name: You can type in anything that describes the account you just made. In this example, we will use UCSD E-Mail.
Click Next and finish up the process. After this you should be all set!
