The word on the street is that Outlook is wanting MFA.  So either you have to turn on MFA or disable ADAL

Fix get them onto MFA or

Close Outlook

Open Regedit

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity

Create REG_DWORD

EnableADAL

Hi Sam,

Based on the error message, the issue is related to Trusted Platform Module(TPM). You need to check whether your TPM works correctly. You try to back up your data and clear TPM. It will reset your security processor to its default settings. For your reference:

For more details about TPM, you can follow the link below:

    I was able to fix this issue by disconnecting my Work account and then reconnecting it. I was receiving the exact same error message and I had tried clearing the TPM and other fixes to no avail.

    Below are the steps I used to remedy the issue:

    1. Navigate to the “Accounts” section of the Settings app and navigate to the “Access work or school” page. Click the account you want to unlink and press the “Disconnect” button. Follow the prompts to complete the account removal process.
    2. Navigate to the “Accounts” section of the Settings app and navigate back to the “Access work or school” page. Click the "+" icon to associate an account.
    3. Enter your credentials and wait for the process to complete.
    4. Launch Outlook and all should be functioning properly.

    after trying so many potential fixes for about three days, this was the one that fixed the problem
