My account has been locked and need to contact Microsoft support person.

If your account has been locked and you need to contact Microsoft support, you can follow these steps:

1. Use the Microsoft Account Recovery Form: Go to the Microsoft Account Recovery form at https://account.live.com/acsr. Fill out the form with as much accurate information as possible to verify your identity.
2. Contact Microsoft Support: If the recovery form does not work, you can contact Microsoft Support directly. Here’s how:
   • In the search bar, type "Get Help" and open it.
   • Type "Chat with an agent" and press Enter.
   • Click the "Contact support" button at the bottom.
   • Choose the products and services for which you need help and follow the on-screen prompts to connect with a live agent.
   • Alternatively, you can select the "Call me back" option to provide your information for a callback.

These steps should help you regain access to your account and allow you to open the files sent to you through Microsoft.
