Managing personal Outlook.com account settings, security, and privacy
Hi,
The screenshot alone does not confirm whether someone completed that check and gained access. Check the recent sign-in activity:
If there is no successful sign-in, your account is secure and the attempt to access your account is unsuccessful. However, secure your account as soon as possible.
Change your Microsoft account password to a strong, unique password. In Advanced security options, select Sign out everywhere.

Make sure Two-step verification is turned on and set up Microsoft Authenticator if you have not already done so, and check that your recovery information belongs to you.
Please let me know if you need further assistance.
