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!

    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.

    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

    We are having this same issue. This is what fixed it for us. Create the following registry entries.

    [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

    Open Regedit.MSC with administrator account and navigate to :

    HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb

    Afterwards create DWORD (32-bit) Value Key

    Rename it with : ProtectionPolicy  and set value to 1

    Afterwards try to open affected 365 App it should force it log in page and enroll again. 

    At this stage Outlook,OneDriveshould work as expected.

    I had hope that this would fix the TPM/prompt for login issue, but unfortunately it did not.  User was prompted for login less than 24 hours after the regedit. :(
