For some strange reason today I cannot send messages from my WLM 2012.  When I click send, I can see the progression of "connecting" followed by "Authorizing" and then I get "Error".  The error box only indicates "failed", nothing more.  I can receive e-mails.  I'm using Windows 7.  The configuration looks correct and I tried the repair option in the control panel for Windows Live Essentials.  I can't solve this one.  Help !!!
