HI All,

Office reinstallation

Tried older Office version

Leave and Rejoined Hybrid AD, we don't have ADFS environment. I get below error, please suggest for any solution

    @karthik palani

    Thank you for your post and I apologize for the delayed response!

    Error Message:

    ERROR_ADAL_WSTRUST_REQUEST_SECURITYTOKEN_FAILED: 0xCAA90014 Server WS-Trust response reported fault exception and it failed to get assertion. WS-Trust response: The requested resource requires user authentication.

    From your error message, it looks like the issue might be that your device wasn't able to get a valid token from the federation service. In order to resolve the Server WS-Trust response error message, you'll have to check your Federation Server settings, and look for the server error code in the authentication logs. For more info.

    Additionally, I found a related issue where a customer only had DeviceAuth configured within the Global Auth Policy, but for Windows to obtain an Enterprise PRT, you'll need to enable FormsAuth.

    I hope this helps!
