Posted on by Balasaheb 700

Hi,

We have created the windows application to perform some operation like connect to Dynamics CRM 9.0 and do some operation.

It is working properly on some the CRM organization but one of the online CRM organization it is giving the below error while connecting.

An unsecured or incorrectly secured fault was received from the other party

We have re-verify that user credentials is correct like user name and password and also time is sync with the machine that we tried to run windows tool.

Also we tried with the updated Microsoft assemblies but still it is giving the same issue.

Is anyone face similar issue and have solution for it.

Waiting for your reply.

Thanks!

Balasaheb

    This is an authentication issue.

    If you are using 9.0 and online, it is suggested you authenticate via Azure Active Directory App with app id and secret and application user credentials.

    Please check the details in the following link

    Hello Dear,

    Greetings of the day!

    In regards to your concern, Please check and confirm that if Multi factor authentication enabled or not.

    If Multi factor authentication is enabled or after enable re disabled, then you have to create app password & use that password instead of your default password.

    You can use the below links for your Reference:
