Cannot Recover Outlook Account Due to Security Block

Hello, I am unable to access my Outlook account (o****@outlook.com) due to a message stating, "Unusual activity detected on your account." When I attempt to recover the account, the process fails repeatedly, displaying an error message. Despite following the recovery steps, I am unable to regain access to my account.

This is the email I use daily, and I cannot understand why it has been blocked. I have been trying for hours, filling out forms and following instructions, but nothing works. Creating a new account is not a viable solution, as I rely on this specific email for all my communications.

I need an immediate resolution to this issue. Please provide a way to unblock and recover my account promptly.
