Hi, I'm John!
It is recommended to add as many 2FA options as possible before going overseas if you were planning to check your email while abroad. This helps avoid security lockouts and ensures you have proper verification methods if you do get locked out.
If your Hotmail account is already signed in on the Outlook app on your phone, you can still access your account there, as it may not be affected by the lockout.
If issue persists, the only option for now is to wait for the full 24 to 48 hours for the lockout to clear completely.
Try not to attempt signing in during this time, as doing so will reset the waiting period back to zero. Once the time has fully passed, you should be able to sign in again without needing to reset your password.
Let me know how it goes after waiting for a full 24 or 48 hours. I'm here to help you further.
Regards,
John J.D.
