Setting up a POP3 account with Mozilla Thunderbird

Setting up a POP3 account with Mozilla Thunderbird 

To set up Mozilla Thunderbird simply:

  1. Open Mozilla Thunderbird. The Mail Account Setup dialog box will open the first time that you open Thunderbird. If the Mail Account Setup dialog box doesn't open when you first open Thunderbird, do the following:
    • On the File menu, select New then Mail Account. 
  2. In the Mail Account Setup dialog box, enter the following:
    • In the Your Name box, enter the name that you want to appear on the "From" line in your outgoing messages.
    • In the Email Address box, enter your e-mail address.
    • In the Password box, enter your password. Select Continue if you're using a Windows or Linux computer or select Next if you're using a Mac.
    • Thunderbird will try to find your account settings. A page appears where you can enter the server settings for your account. If you don't click Stop quickly, the page may include this message: "Thunderbird has found the settings for your account." However, the account settings it locates won't be correct; you must configure the settings yourself. 
  3. In the Username box, type your complete email address. For example, myname@mydomain.com.
  4. To configure the settings for the incoming server:
    • Next to Incoming, enter the name of your incoming server. If you are using POP, this will be outlook.office365.com.
    • Select POP on the dropdown menu if not already selected.
    • Next to the incoming server name, type 995.
    • Then, in the drop-down list next to the port number, select SSL/TLS.


  5. To configure the setting for the outgoing server:
    • Next to Outgoing, enter the SMTP server name smtp.office365.com
    • Next to the outgoing server name, type 587
    • Then, in the drop-down list next to the port number, select STARTTLS


  6. Select the Re-test Configuration button. If you entered the correct settings, you'll see the following message: "Thunderbird has found the settings for your account." or a green button will appear to the left of each server name. Select Create Account. You should now be able to send and receive emails.


Note: If you're using POP, under Server Settings, you may want to select Leave messages on the server. Once selected, a copy of your messages will be kept on the server allowing you to access your messages from a different mail application.
