Error code 80090016 Trusted Platform Module has malfunctioned.

When I try to add a new Office 365 email to my outlook I get the error below.   I think it's because of my "Work or school account" which I want to remove. I'm not sure how my email was signed up for this second account. I set up this computer for home use only, I won't be using any of the Microsoft Azure features. 

My question is, what will happen when I remove my “work account” and leave my Microsoft account?  Everything is backed up on Onedrive, I just don’t know what to expect because when I went to remove it, it warned me about losing data and settings.

Any help would be appreciated. Thank you!

    Create these registry entries and it should resolve your issue.

    [HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity "DisableADALatopWAMOverride"=dword:00000001

    [HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity "DisableAADWAM"=dword:00000001

    This worked for me. Its only been about 2 hours and I have not received a pop up asking for a password yet. Before I got them every 10 mins or the app would not log in. I'll give it 24 hours and update.

    I still get the password sign in screen. Just not as much. Windows security is always popping up asking for outlook password. Microsoft needs to fix whatever they broke with office 365 with another Windows update
