Sending, receiving, and organizing email in Outlook.com
Hi, I'm John! I will help you with this.
Usually, that message appears when the Microsoft account already exists, but the sign-in details being entered may not match the original account.
To help narrow down the issue:
- Are you trying to sign in on the Microsoft sign-in page, or are you trying to create the account again?
- Have you tried signing in directly at https://account.microsoft.com to test if the account is still accessible?
- Do you still have access to any recovery email, phone number, or device previously linked to that Outlook account?
- What exact message do you see after entering the email address?
Any additional info about the issue you can provide will be helpful in diagnosing and resolving the issue.
