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:

    Hi Richard,

    Looks like Susan's solution is the best and easy way. Can you please tell me the Identity DWORD (32 bit) should be named as EnableADAL and set the value to 0??

    Thanks,

    Subash P

    Dear Susan

    Many thanks from a grateful follower of your advice. As usual, the word "upgrade" when applied to new software versions (in this case Windows 10.1903), included some involuntary downgrades. Your advice was admirably short, comprehensible and, most of all, effective.

    Well done

    xx

    Richard
