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.

    We see problems like this a lot usually removing all the work/school accounts and signing in to any app (word, outlook, etc) resolves any error message. Also when signing in unchecking let my school/work manage my machine can prevent issues in the future.

    I managed to fix the problem via signing in with the same work organization's credentials in the Settings > Accounts > Access work or school. BTW I have no idea what caused the issue

    This is what worked for me. I had a client that had this problem on 3 PCs and this simple solution fixed all of them. I had tried the other solutions of deleting the contents of the Ngc folder or renaming the other AAD folder and they didn't work. But signing out and back in worked beautifully.

    ~Issue fixed in one specific use case~

    I had this same issue with a machine I had reimaged and then used my organization's User State Migration tool to restore a backup from another computer. This tool basically copies everything from the user profile on one computer into the next, including AppData, etc.

    After some troubleshooting, I found the user state backup was the issue, specifically in the Appdata folder. 2 workarounds worked:

    1. Logging into the account before running the backup tool
    2. Backing up files from the previous machine manually, being careful to not copy over the AppData folder.

    I know this is pretty case-specific and doesn't get to the file location of the root issue, but I hope it helps for some people.
