Step 3 - Manually Configure
Check the box at the bottom for Manually configure server settings or additional server types.
Note: Depending upon whether any previous accounts have been setup in Outlook, the next couple screens may vary in order, but are nearly identical.
You will see either a Choose Email Service or a settings window with Manually configure server settings or additional server types. The key point is to check the box to Manually configure server settings or additional server types and select the type of email service for the account (POP/IMAP).
