Note If Windows Messenger is running, you have to sign out from the MSN Messenger.
The version of Windows Messenger that is installed with Windows XP SP2 is associated with the default e-mail program that is set in Microsoft Internet Explorer. The default e-mail program may be Outlook, Outlook Express, MSN, or Windows Live Hotmail. When you click the My E-mail Inbox on the File menu in Windows Messenger, the default e-mail program will start. The My E-mail Inbox will not automatically sign you in to your Windows Live Hotmail account.
