Unlink personal Microsoft account from egde Windows Server 2012 r2

Question

In the last few days, I added my Microsoft account to Edge on a Work PC that has Windows Server 2012 R2. When I when i finnshed  the things I was doing, I logged out and removed the account, but my account still suggested “choose an account” and can be signed in without a password..  I have been trying for two days to remove it from the suggestion. I tried everything I found on Google. I even tried uninstalling Edge, removing the folders %localappdata%\Microsoft\Edge and %Program Files% (x86)\Microsoft\Edge, and reinstalling Edge. but the account is still suggested for login. I found someone who faced the same problem Unlink personal Microsoft account from Windows Server - Microsoft Q&A but didn't fined answer. Keep in mind that clean installation is the last solution I will try, so I want you guys to suggest other solutions.
