If you locked yourself out of your own computer then nobody but a network admin would be able to help you. MS doesn't have a magic backdoor into your system (at least that I know of). If they did then anybody could use it.
Not sure what you mean by "locked out". If you mean Windows is saying your account is locked then you configured your machine to enable a lockout policy (not good for a local machine). When setting up a lockout policy it generally requires a reset time. You could set it to none but that would be very bad. I think the default is 15 mins so if you wait 15 mins you can try logging in again.
If you forgot your MS password and locked out your MS account then you can probably go online to reset it. However you'll need to know the original password. If you don't remember the original password and you didn't set up a recovery email or equivalent then I doubt there is anything you can do about it. You should always ensure you have a recovery email tied to your MS account (that isn't a MS account).
If you absolutely cannot get back into your account and there is no way to recover then the final option is to reinstall/repair Windows. During reinstallation you can create a new local admin account. Once you're back into Windows you can gain access to the data on the original drive. Just be sure that you don't format or wipe the drive with the original data when restoring. If you had any encrypted data associated with the lost account then that data is gone but any per-user data can be retrieved using an admin account.
