Hi,
Thank you for sharing, I'm here to help. If your account is hacked, Account Recovery is your last resort. You can submit the Account Recovery Form up to twice a day from a similar location and a device you've previously accessed your account from. I recommend continuing to try the Account Recovery Form, as it's the only way to restore access to your account.
Use this device when submitting the recovery form. Microsoft systems can detect device fingerprints linked to your account, which will help with verification.
Open any web browser on your device and go to this link: https://account.live.com/acsr
Enter your locked account email address. Then, in the "How should we contact you?" section, enter an email address you currently have access to (Gmail, iCloud, etc.).
Microsoft will use this alternative email address to contact you.
We look forward to helping you. Please let me know if you need further assistance. If the answer is helpful, please click "Accept Answer."
Sincerely,
Jansher
