The problem maybe more widespread. I am running win 7 pro with Win Live Ess 2011. I have 3 accounts gmail, hotmail, shaw.ca and I cannot reply or forward any.

I get an error message not a redline. When i try to repair Essentials, it gets almost complete then announces it has lost internet connection which has happened 3 times in a row. Connection is good each time. 

I wonder if it is connected to a firewall issue in a bad update by MS?
