Remove Deactivated Work Or School Email Account

I have an organizational email account that has been deactivated, current guides online say the following:

"If you need to remove an account from your PC:

1. Select Start > Settings > Accounts > Access work or school .
   
2. Select the account you wish to remove, then select Disconnect
   
   ...."
   

However, the only option presented at this section is "Manage" which forwards me to my organization's page to login. The account has since been deactivated with no way to get to the next step.
I have been getting notifications from my system that "There is a problem with a work or school account click her to fix now" but obviously can't login to remove the account from the system.
Is there a work around to remove the account without logging in?
