Step by step guide on how to configure Mozilla Thunderbird 8.0 using Office 365 Email.

Set up email using Mozilla Thunderbird 8.0

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, do the following:

   1. On the Tools menu, click Account Settings.

   2. On the Account Settings page, under Account Actions, click Add Mail Account.

2. In the Mail Account Setup dialog box, do the following:

   1. In the Your Name box, enter the name that you want to appear on the "From" line in your outgoing messages.

   2. In the Email Address box, enter your email address.

   3. In the Password box, enter your password. Click Continue if you're using a Windows computer or click Next if you're using a Mac. Thunderbird will try to find the settings you need to configure for your account.

3. Click Stop, or wait for Thunderbird to try to find your account settings. You’ll see the message: "Thunderbird failed to find the settings for your email account."

4. The IMAP check box, next to Incoming, is selected by default and is recommended. In the Server hostname box, enter the name of your incoming server - outlook.office365.com

   Note: Leave the Port option set to Auto. Leave the SSL and Authentication options set to Autodetect.

5. In the Server hostname text box, next to Outgoing, enter your SMTP server name - smtp.office365.com

   Note: Leave the Port option set to Auto. Leave the SSL and Authentication options set to Autodetect.

6. In the Username box, type your complete email address. For example, tonysmith@contoso.com.

7. Click the Re-test button. If you see the message "The following settings were found by probing the given server,” click Create Account. A page opens that lets you view or change other Thunderbird settings.

   Click OK when you've finished viewing or changing the settings.
