Note Microsoft account is still called Windows Live on Windows Phone 7. So, if you're on a Windows Phone 7, your error message will show "ACTIVATE WINDOWS LIVE," and it will refer to your account as a "Windows Live ID" instead of "Microsoft account."
Each Windows Phone is created with an activation code as part of the manufacturing process. In rare cases, a new activation code is required to complete the Microsoft account sign-in process. This is why you're asked to enter a new activation code when signing in with your Microsoft account for the first time.
Note The appearance of the Activate Windows Phone screen does not reflect a problem with the Microsoft account that you're trying to sign in with.

Doing this may prevent your new code from working.
Note You can tap Skip on the Activate Windows Phone screen, which lets you continue to use your phone until you get a new activation code.
2. Return to the Activate Windows Phone screen and enter your new activation codeYou'll be able to enter your new activation code the next time that you use a Windows Phone feature that requires a Microsoft account sign in (such as playing a game on Xbox Live, downloading an app from Windows Phone Store or Marketplace, or adding a Hotmail or Outlook email account). In any of these instances, you'll receive a Microsoft account sign in screen, and then you'll be asked to enter your new activation code.
