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!

    I managed fix the issue by going into the program folder and running the scanpst.exe. Soon as I closed Outlook and ran the exe the error is no longer being generated when signing into Outlook.

    This is not a fix. It's a workaround. And a sloppy one that will cause you issues in the future. You're basically relaxing your security settings.

    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

    This did the trick for me!!!
