Windows 10: After Removing School account, Still prompted to sign into it.

While I was enrolled in school, I had a school Microsoft 365 account. I am no longer in school and now have a personal Microsoft 365 subscription. I have removed the school account from my computer, but I am still prompted to sign into that school account every time I open something. I have tried uninstalling and reinstalling all office apps from my account dashboard, and I still get the same problem. How do I get rid of all traces of this account, it's incredibly annoying.

Remove account

I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:

 

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?

 

Work or School Account Trying to Sign In

I connected my school Microsoft Account on the Microsoft Office app. I have removed my school account, however, when I use the app, Microsoft 365 tries to have me sign in with my school account. Funny thing is... I'm already signed in with my personal 365 account. I would like to permanently remove my school's account so that 365 DOES NOT try to have me sign in. How do I do this?
