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!

    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)

    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.

    To Narrow down the folder. I renamed the "LocalState" Folder in %userprofile%\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\ and Outlook started to work again.

    Hi Anna

    I see that you are listed as a Microsoft Agent and moderator for this forum.  I think that means that you are a Microsoft employee, and I would hope that means you have some means to provide feedback to a customer support group at Microsoft.

    Would you please find some way to add this "password amnesia" and TPM error to some development list that someone actually cares about?  It seems that the masses that are seeing this critical error and loss of functionality are unable to wake anyone at Microsoft that can do more than flip to the appropriate page in the customer service guide and read their sincere apology that we are experiencing this issue.

    As I mentioned in a previous post I have worked for a couple larger software companies including as a Field Product Manager.  I have never seen nor do I ever care to see again the multitude of walls and barriers that Microsoft has erected to keep valuable feedback from returning to the person(s) in charge and destroying their fragile view that these problems do not ultimately rest on their shoulders.

    As users we have tried a multitude of hacks, prayers, and probably even some violence against our computers to try to fix these problems.  These issues are repeatable and verifiable.  These issues have not been fixed since the initial rollout of build 2004.  I can't begin to estimate the amount of collective time and effort that has been expended by the many users and IT people trying to fix these problems.

    Can you help in some way?
