Signing in has nothing to do with being able to read, receive or send mail. It determines which contacts list and calendar to load. It also allows you to send photo email if you want to.

When viewing your message list, press Ctrl-Shift-O for Options. On the Connection tab, click Stop signing in. Accept the warning, then close down Windows Live Mail. Wait a few minutes, then start the program again; you should not see the sign-in dialogue.

You can now use the right-most button on the Home tab of the ribbon to sign in if you want to use the contacts and calendar associated with your Microsoft Account. If you select Remember me and sign me in automatically, you should not have to enter your credentials each time you start the program.

I am not able to click/access the 'stop signing in' tab.  It is grayed out. Now what???

A few weeks ago my Windows Live Mail program began to keep asking for my login and password, not the windows Live login and password, but my ISP login and password.

 My ISP says it's a windows OS problem.  

I have the 

options > email accounts > servers > remember password CHECKED.

I don't want to always log in to Windows Live to access my ISP email account. 

Please help.

Thanks,
