Managing personal Outlook.com account settings, security, and privacy
Hi segert, it's Bryll
I genuinely understand how worrisome this can be, but I want to assure you that you're not alone.
I want to inform you first of all that Microsoft accounts are handled by a full automated server, and we cannot and do not have access or visibility to any account information but allow us to help you as best as we can.
We have carefully reviewed your post and it shows that your Microsoft account is quite secure considering that you have a strong password and a two-step verification feature enabled. Out of curiosity, you'd like to know why your Microsoft account's sign-in activity page shows unsuccessful sign-in attempts from unknown IP addresses.
This can sometimes happen if one of your devices that your Microsoft account is signed in to is connected to a VPN network. Failed login attempts from unknown IP addresses are also the result of hackers or bots trying to gain access to your Microsoft account. They may have obtained your email address as a result of a data breach or phishing scam, and are trying to guess your password or bypass two-step verification. However, if you have a strong password and have enabled two-step verification, you've already taken steps to protect your account from unauthorized access.
I know this might not be a true fix, but you might put into consideration in accessing your Microsoft account after 48-72 hours. Should problem remain, we recommend in using an InPrivate browser tab or a different device while connected to a different internet network like a mobile data hotspot for accessing the account to see if it would go through.
If in any case, you will notice bank charges made by Microsoft that you do not recognize. If you see the error message "Help us secure your account" when you sign in to your Microsoft account. If any changes have been made to your Microsoft account's email alias. If your Microsoft account has been successfully connected to a device that you don't recognize and your Microsoft account security information has changed, we recommend for you to coordinate with the Chat/Phone support technicians immediately so that the necessary action can be taken using their advanced tools:
Please follow these steps below to speak with a Chat/Phone support technician:
Visit this website: Contact - Microsoft Support
From the description box, type Chat or Phone support then scroll down and press Contact Support

Press Confirm and you will be placed in queue. Please wait for a Chat or Phone person technician to connect with you.
Hopefully, you'll be reunited with your account as soon as possible.
