I'm trying to migrate from Outlook Express & Windows XP to Outlook on a new computer running Windows 8
 
I've set up a Microsoft a/c & an Outlook a/c using the 'old' computer & mastered copying my contacts & emails from Outlook Express to Outlook. 
 
However, when I click the email tile under Windows 8 & try to register my Outlook a/c quoting my email address & password it returns the message:
  "We couldn't find settings for <my email address>.  Provide us with more information & we'll try connecting again"
The additional information requested is Domain & Username.  I have no idea what a domain is & where I wd find what mine is & am not aware I have an Outlook username
 
I have managed to access my Outlook a/c under Windows 8 by going to outlook.com via Internet Explorer.  However, when I send a test message it doesn't arrive in Outlook - presumably because my Outlook a/c isn't registered on the new computer
