Open Outlook 2010 and click on the File tab on the top left of the page.
Click on the Add Account button under Account Information.
On the first page that opens, fill out the following information:
Your Name: Enter in the name you want people to see when you email them.
E-mail Address: Enter in your full email address.
Password: Enter in your email address password. Email passwords are case sensitive.
Retype Password: Enter in your email address password again.
Click the radio button next to Manually configure server settings or additional server types.
Click the Next > button to go to the next page.
Select the radio button next to Internet E-mail and then click the Next > button to continue to the next page.
Fill out the following information.
Under Server Information:
Under Logon Information:
Click the More Settings button on the bottom right of the page to go to the next steps.
Under the Internet E-mail Settings window, click on the Outgoing Server Tab.
Check the box next to My outgoing server (SMTP) requires authentication. Then make sure the radio button next to Use same settings as my incoming mail server is selected.
Click the Advanced tab and change the Outgoing server (SMTP) port number to 587.
Under the Advanced tab's Delivery section, make sure the box next to Leave a copy of messages on the server is checked if you want to be able to see your old messages when you check your email from EarthLink Web Mail or on another computer.
If you want to prevent your mail storage from maxing out, you can leave the check box next to Remove from server after X days checked. By default, this is set to 14 days. Unchecking this box will leave all mail on the server until you delete it from the server. Checking this box will cause messages older than the number of days selected from the server.
You can, alternatively, leave the Remove from server after X days option unchecked and check the Remove from server when deleted from 'Deleted Items' option checked instead. This will delete mail off the server when you delete it from Outlook's Deleted Items folder.
Click OK to close out of Internet E-mail Settings.
Click Next> on the Add New Account Window.
A Test Account Settings window will open to check your email settings. If either test fails, you will need to go back and check your email settings. If both test pass, click the Close button.
Click Finish. You have completed your Outlook 2011 email setup.
Here is a video walk-through of the setup process. You can pause using the controls underneath the video at anytime.
