For several hours on October 2nd and October 3rd, 2014, customers visiting http://www.msn.com who clicked Sign In and then clicked Sign up to create a new Microsoft account may not have had their account created correctly. As a result, customers may see one of the following errors when attempting to sign in:
If your experience fits the scenario above, attempt to reset the Microsoft account password. Click the I can't sign in link next to the Microsoft login box and follow the instructions provided. If you do not recognize the security information questions provided on the account, unfortunately that email address is already taken and you should create a new account using a new email address.
Create a new Microsoft account by visiting http://live.microsoft.com and follow the on-screen instructions to create an account. If you attempt to create a new Microsoft account, and the email address is not available, you will need to use a new email address that has not previously been used to create a Microsoft account.
