I already had a personal account and Office apps, but could not get rid of old connection to work school account. Windows kept saying I had a problem with the work school account, but I was avoiding logging in.
I had to log in my work account to see it in the Accounts > Access Work or School so it could be disconnected. The Disconnect button appeared and I used. Did not have any further prompting about alternative account since my personal account was already in use and my main account.
I do not know how you would work this if you no longer had access to the associated Work or School account. But since I did, a combo of the above and the linked article was the solution
Thank you Kapil.
