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!

    Hi all, I've had the same issues since 4th January when my PC did an automatic update to Windows version 20H2...constant requests for password sign ins, trusted platform errors, etc. Inspired by some earlier posts this how I fixed it and I know very little about how PCs work.

    I did this by removing my work email from Outlook profiles via the Control Panel and also from ‘Accounts/Access work or school’ under Windows Settings. I then temporarily disabled the Trusted Platform Module via Windows Settings.

    I then set up ‘sign in with Hello Face’ since this is one of the prompts I was getting from the Work account.

    When I signed back in to my PC there was no need for a password at all since I had face recognition and no requests for email sign in. I then added back my work email to my one (single) profile (Outlook) under which I already had my personal Outlook account and my business account using an Imap sign up.

    For Aneta who asked in an earlier post, you won't lose any emails from your work account since everything is on the cloud. The emails all come back once you add the email under the cleaned up profile as above,

    All seems to be working again since Saturday evening so fingers crossed.

    Good luck and I feel your frustration with MS.

    I almost agree. It seems harsh but this is a pretty important piece to have to mess around with as we have had to do. As a Side note, I just bought an M1 Macbook.

    I have tried above steps - no success.

    I have the impression that we, as community, try all possible ways to solve the problem on Microsoft's behalf.

    Am I wrong? Is this the right way? Luckily for me I am also a mac user and can easily switch. This however does not solve the problem for me as a Win user.

    I tried quite a few things including:

    1. Deleting the ngc folder.
      1. Did not work immediately.
    2. Clearing the TPM credentials on two places.
      1. Did not work immediately.
    3. Going to Settings -> Access Work or School -> Clicking on my work account -> Click "Disconnect".
      1. This seemed to work.
      2. The account disappeared and reappeared but was not removed.
