I have had to take my pc back to factory settings and although much is now ok I cannot access my Windows Live email.  so I installed Outlook Express.  It tells me I am installed but wont allow me to log in.  It asks for a Microsoft ID which I don't know.  Help!!!  I am loads of emails but I cannot get to them

Since the outages on mon and tues January 2013 I have not been able to access my hotmail acct via my andriod phone. I have done everything i can do outside of resetting my phone back to factory settings to fix the issues, it for erver stays in loading and it will not send out as well. I did dl microsoft+7 and tried that as well and got an error code 100.
