In the last 2 days I've only been able to go to the inbox page, but can't change folders, open mail, etc.
I have the Ghostery add on - it was blocking Microsoft Atlas.
"Microsoft Advertising operates: AdECN, Atlas ProfitBuilder, Microsoft adCenter Conversion, Microsoft Analytics, Microsoft Atlas, Microsoft Notice, MSN Ads"
Anonymous (Ad Views, Browser Information, Cookie Data , Date/Time, Demographic Data, Hardware/Software Type, Interaction Data , Page Views , Serving Domains)

As soon as I whitelisted Ghostery I could use live once again. Pfft M$ forcing their will once again.
Note that Adblock Plus and all other protective functions are enabled.
