Managing personal Outlook.com account settings, security, and privacy
I understand why this appears contradictory. Receiving a security code only confirms that the recovery email address or phone number is associated with a Microsoft account. The masked username shown afterward may be a different sign-in alias.
Please compare the visible characters and domain in the masked username with the address you are trying to use. If they differ, try signing in with the corresponding alias or another email address or phone number previously linked to the account.
If the masked username appears correct but Microsoft still says the account does not exist, please contact Microsoft Support:
- Open Contact Microsoft Support.
- Click Show expanded list of products
- Select Outlook > Get Home support
- Type Account Recovery in the search box, then select Get Help > Contact Support
- If you can’t sign in to the affected account, sign in with a different Microsoft account to access support options
- Under Products & Services, select Other Products > Manage Account Security then choose Chat with a support agent via web browser
