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:

Regards,

Carlos

    I received this error from outlook only ( I was able to use Skype for Business, as well as email on my phone) the day after changing my AD password, but don't even have TPM enabled, let alone have one installed. Ergo, this reg. entry did nothing for me.

    On a off-chance, I logged out of all Microsoft accounts, disconnected from our LAN and connected to our Wifi, then attempted to login to Outlook.

    For whatever reason, this resolved my issue. FWIW.
