Cannot find all emails/addresses after conversion to Outlook.

Within the last 2 days I had to completely reformat my computer back to factory settings.  Now when I sign in to hotmail it comes up through Outlook.  I had several email addresses under hotmail and msn which would all come up in the same place when I signed into hotmail.  Now I only get the main hotmail address but not the msn address or any other hotmail addresses.  How can I access those other addresses?Within the last 2 days I had to completely reformat my computer back to factory settings.  Now when I sign in to hotmail it comes up through Outlook.  I had several email addresses under hotmail and msn which would all come up in the same place when I signed into hotmail.  Now I only get the main hotmail address but not the msn address or any other hotmail addresses.  How can I access those other addresses?
