Unable to Access Outlook Account for 1 Year Due to Blocked Password and Old Phone Number

I haven’t been able to access my Outlook account for a year. Despite entering the correct password, my account is blocked, and my recovery phone number is outdated, so I can’t reset it. All my important accounts are linked to this Outlook email, making it impossible to manage essential tasks. I urgently need guidance on how to recover my Outlook account and regain access. Any assistance would be greatly appreciated.
