First of all, I am talking about Windows Live Mail Desktop beta but you are talking about Windows Live Mail beta. No, no don't get angry but there is something wrong here really.
For example I can't open my program without signing in, but the documentation you quoted says it was possible to open it without signing in. Also I have checked the updates for my computer but it didn't find anything related to Windows Live Mail Desktop (Windows Live Mail). I don't know why it didn't find. If you used WLMD once, I wonder if you got a notification for the update to new Windows Live Mail program or not. Because it seems that I have to download that new program from its own page on ideas.live.com, I can't get it with an update of Windows.
And after a couple of tests, I am 100% sure that WLMD is the reason of my problem (Not a problem actually
). Thank you for your effort to help.
