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!

    Here's the solution.

    1. Log in under another admin credentials or you may go to \PC-name\c$
    2. Rename the following folder:

    C:\users$dir\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy

    To:

    C:\users$dir\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy.old

    One of my users got this error code 80090016 when trying to log into office applications on laptop. They were able to log into office 365 online just not desktop app on this particular PC. They could login to app on another device and other users could login into app on this laptop (obviously different user logins profiles).

    So I removed that user's profile from Windows, had them login and all works now.

    Remove profile: (windows 10)

    Be sure to backupanything in user's folders: desktop, documents, pictures, etc.

    login to Windows as another user with local administrator rights.

    Control Panel, System, Advanced System Settings (on right menu)

    from System Properties window that opens; click Setting button for User Profiles.

    Select profile to remove, click delete.

    restart Windows, have user login (first time login experience)
