Hi,
Please try to check if you have another way to sign in on the password page. If you have this option, please try another method to sign in. If you can sign in or the account is currently signed in on your other device, please change your sign-in preference.
If you do not have this option, please try to sign in again after 24 hours. Please refrain from login attempts within 24 hours. To ensure adequate waiting time, it is advisable to extend the waiting period slightly.
If you still experience the same issue after 24 hours, your account may have been blocked due to suspicious activity. Please refer to this link: Unblock my Outlook.com account.
Also, try to fill out the Request for Account Reinstatement
If you require further assistance, please don't hesitate to let me know.
Stay Safe!
