LSUMail: Set up Thunderbird for POP or IMAP

This article has not been updated recently and may contain dated material.


This article explains the steps for setting up Mozilla Thunderbird as either a POP or IMAP client accessing an LSUMail Account.   The screen shots in this article are those of Thunderbird 6.0.2.  What you see will depend on your version of Thunderbird.

POP/IMAP e-mail programs such as Thunderbird will access your LSUMail messages but contacts and calendar entries are kept on your local computer and not synchronized with the contacts and calendar items your LSUMail  account.

For Windows and Mac Users, ITS recommends using Microsoft Outlook or the Outlook OWA (

PLEASE NOTE: This will only work ON CAMPUS. Conditional Access will not support IMAP off campus.



1. Identify your POP, IMAP and SMTP settings for LSUMail.

2. Download and install the latest version of Mozilla Thunderbird.

3. Set up Thunderbird as either a POP or IMAP client with the information you obtained from Step 1.

  • IMAP clients will keep your e-mails on the mail server and just show you the contents.  This provides more flexibility and other e-mail apps will be able to get to your messages.  
    • **ITS Recommends Using IMAP**
  • POP clients will download all your e-mails to your local machine and usually remove the copy from the mail server.
    • We DO NOT Recommend using POP connections because deleting e-mails from the mail server will prevent other e-mail programs from seeing them.

4. Open Thunderbird.

5. On the Front Screen, select Email under Create a new account to create a new mail account.
