Sending, receiving, and organizing email in Outlook.com
Hi! My name is Aj and Im an Independent Advisor here to help! I understand your frustration. When it comes to log in issue its better if you use the "Sign in Helper" tool first here https://support.microsoft.com/en-us/account-billing/help-with-the-microsoft-account-recovery-form-b19c02d1-a782-dee6-93c3-dc8113b20c42, but if it doesnt help then proceed in submitting an account recovery form again here https://account.live.com/acsr and use the guide on how to properly submit the account recovery form.
To contact microsoft support directly go here https://support.microsoft.com/contactus then choose "Account & billing" and then "Microsoft account". Sign in if possible, or click "Cant sign in?" to continue as a guest. From there you'll see options like virtual agent, chat with support, or in some regions, request a call back.
Just note that Microsoft agents are not allowed to send password reset links or change account details directly. All recovery must go through the Sign-in Helper or the account recovery form. But you can still try.
