How to remove account that I no longer have access to?

I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.

What works when the Account has no Remove button in the Email and Accounts section, is to look below to Work and School accounts to choose the same account, then Remove or Disconnect to allow the Remove button to light up above. 

You need to be signed in as an Administrator to delete an account. If you don't have Admin powers then you can try enabling the built-in Admin to do this, but if it requires a password you'll need to access it from booted media which is the only method that doesn't require a password: https://www.tenforums.com/tutorials/2969-enable...

From the Admin account if you don't have access to it in Email and other Accounts, type netplwiz in Start Search, right click to Run as Administrator, highlight the unwanted account to Remove. Report back results.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

Try the following steps to delete a user account from the Control Panel.

Right click on the Stat button and select the Control Panel.

Click on the User Accounts and Click on the Manage another account link.

If prompted by UAC, click on Yes.

Click on a user account which you want to delete.

Click on the Delete the account link.

Click on Delete Files or Keep Files for what you want to do with the user account's personal files.

Click on Delete Account to confirm.

When finished, you can close the Control Panel if you like.

Note: You must be signed in as an administrator to be able to delete a user account. You will not be able to delete a user account that is currently signed in. You will need to sign out the user first. Be sure to always have at least one enabled administrator account on the PC to avoid not being able to perform actions that require administrator rights.

Sounds like this account was the original account that setup your profile.

Best solution that does NOT require a reset is to create a new account to login to then move your data over to that new account.
