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'm not sure what $dir was in the 1st path you posted.

    However, under my AppData folder, I drilled down and found the Microsoft.AAD.BrokerPlugin... folder.

    I deleted everything. It didn't allow me to delete everything at first. However, after going all the way to the final folder, I was able to delete the two files, and then all the upward folders until I was able to successfully delete the AAD folder.

    Without rebooting, I opened up Outlook 365 and was able to successfully created a new profile to check my 365 mail that I'm able to get successfully on all my other devices.

    It's nice to have things finally working again.

    Thank you for the AAD folder deletion suggestion. It worked just fine for me.

    1. Exit Outlook and Teams
    2. Open a command window with admin access (run as administrator)
    3. Type the command dsregcmd /leave and press Enter
    4. Type the command dsregcmd /join and press Enter

    I was able to clear the error by going to "Accounts" in settings

    Then, "Access Work or School", find your "Work or School account" and select "Disconnect"

    Then select "Connect"

    Then log back in with your account

    No error afterwards.
